It must have something to do with the main subject of the lesson,

or with all the graphs that come up in the process of the lesson.

It's hard to tell without knowing SOMETHING about the lesson.

**Answer:**

1) For

A) **Domain=**

B) **Range= **

C)** y-intercept **= 0

D) **Asymptote= **No asymptote

2) For

A) **Domain=Domain=**

B) **Range= **

C)** y-intercept **= None

D) **Vertical Asymptote:**
x=0

**Step-by-step explanation:**

** Given : ** and

**Refer the graph attached. **

1) In equation (1)

→**The domain is the set of all possible values in which function is defined**.

y=5x is a linear polynomial defined on all real numbers.

**Domain=**

→**Range is the set of all values that function takes.**

It also include all real numbers.

**Range= **

**→y-intercept- Value of y at the point where the line crosses the y axis.**

put x=0 in equation y=5x we get, y=0

Therefore,** y-intercept = 0** (We can see in the graph also)

**→An asymptote is a line that a curve approaches, but never touches**.

**Asymptote= **No asymptote

2) Now in equation (2)

**Domain=**

because log function is not defined in negative.

**Range=**

**y-intercept **- None

**Vertical Asymptote:**
x=0

**Answer: The correct reason is (B) each input value is mapped to a single output value.**

**Step-by-step explanation: **The given statement is:

"The graph of a function never has two different points with the same x-coordinate."

We are to select the **correct reason** for the above statement.

The definition of a **FUNCTION** is as follows:

In simple language, **a function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.**

That is**, if y = f(x)** is a function of a variable 'x', then we have

**(A) **The first statement is **"the graph of a function cannot be a straight line."**

The statement is **false**. For example, let us consider y = x + 2. Obviously, it is a function because every value of 'x' will result in only one value of 'y'.

**Also, the graph here will be a straight line as shown in the attached figure (1).**

**(B)** The first statement is **"each input value is mapped to a single output value."**

**The statement is true according to the definition of a function.**

**(C) **The third statement is **"each input value is mapped to more than one output value."**

The statement is** false** by the definition of a function.

**(D)** The fourth statement is **"the graph of a function is a vertical line."**

The statement is** false**. For example, if we consider the **vertical line x = 2. **Then, we see from the **attached figure (2) that the points (x, y) = (2, 1), (2, 0), (2, 3), etc. all lie on the line.**

This shows that **one input value leads to infinitely many values of 'y'. **Hence, this vertical line cannot be the graph of a function.

**Thus, (B) is the correct statement. **

For the first line:

m = (-5 - 0) / (0 - 2.5) = 2

For the second line:

From the given equation,

m = 2

For the third, using the given coordinates (-1,3) (1,7)

m = (7 - 3) / (1 - (-1)) = 2

Therefore, all the slopes of the lines are 2 and none of them have the smallest slope compared to the others.

m = (-5 - 0) / (0 - 2.5) = 2

For the second line:

From the given equation,

m = 2

The formula of the function would be:

y = 96000(1.07)^t

The graph is an exponential function with y-intercept of 9600. The curve goes upward indefinitely as the value of time increases.

Therefore, from the choices, the statements that apply to the graph are:

-The graph of the function begins at y = 96,000.

-The graph of the function shows the exponential growth.

y = 96000(1.07)^t

The graph is an exponential function with y-intercept of 9600. The curve goes upward indefinitely as the value of time increases.

Therefore, from the choices, the statements that apply to the graph are:

QUESTION POSTED AT 20/01/2020 - 01:22 PM

First, we inspect what type of sequence is the order of the coordinates:

a2 = 1

a3 = 2

a4 = 4

Getting the difference,

a3 - a2 = 1

a4 - a3 = 2

The differences are not equal; hence, the sequence is not arithmetic.

Getting the ratio:

a3/a2 = 2

a4/a3 = 2

The common ratio is 2. Using the general form for a geometric series:

an = a1 r^(n-1)

If n = 2

1 = a1 (2)^(2-1)

a1 = 1/2

So,

an = (1/2) (2)^(n-1)

The answer is the first option.

a2 = 1

a3 = 2

a4 = 4

Getting the difference,

a3 - a2 = 1

a4 - a3 = 2

The differences are not equal; hence, the sequence is not arithmetic.

Getting the ratio:

a3/a2 = 2

a4/a3 = 2

The common ratio is 2. Using the general form for a geometric series:

The first thing you have to take into account is the definition of the axis in the complex plane.

We have then:

The vertical axis represents the imaginary part.

The horizontal axis represents the real part.

We then have the following number:

-14 - 5i

Since the real part and the imaginary part are negative, then the number is located in the third quadrant of the complex plane.

For a box shown in the images, to see the more cost-effective option, one has to simply compare which of the two boxes has the large volume. This can be done by multiplying the length, width, and the height to find the volume. This is shown below:

Box A:

Volume = 2 * 3 * 4 = 24 ft^3

Box B:

Volume = 2 * 5 * 2.5 = 25 ft^3

Therefore, the second box is the more cost-effective of the two.

Box A:

Volume = 2 * 3 * 4 = 24 ft^3

Box B:

Volume = 2 * 5 * 2.5 = 25 ft^3

**Answer:**

A) Price= 1617*Year - 3.116e+006; B) 150340$ By 2020

**Step-by-step explanation:**

We have a data set of 7 x, y pairs, this data set can be modelled as line, applying a linear regression calculator we found that the trend line can be modelled as Price= 1617*Year - 3.116e+006

Attached you will find the regression results where x is the year variable and Y is the price. If we now plug year=2020 in the equation we have:

Price=1617*2020-3.116e+006 = 150340$

The best answer to the problem given above would be letter A. The speed of the skater travels at 10 miles per hour constantly. I got this through employing the formula, y2 - y1 / x2 - x1 and computed using the points.

which is:

v = (25 miles -10 miles) / (2.5 hrs - 1 hrs)

v = 10 miles per hour

Thus, the answer is 10 miles per hour.

which is:

v = (25 miles -10 miles) / (2.5 hrs - 1 hrs)

v = 10 miles per hour

Thus, the answer is 10 miles per hour.
