A. The data represent an exponential function because there is a

common ratio of 4.

B. The data represent a linear function because there is a common

difference of 9

C. The data represent an exponential function because there is a

common ratio of -

D. The data represent a linear function because there is a common

difference of -9.

answer: what is the question you're trying to ask?

step-by-step explanation:

The common difference is same = d = -9

Therefore, the data represent a linear function.

Step-by-step explanation:

Given the table

x y

1 4

2 -5

3 -14

4 -23

5 -32

Finding the common difference between all the adjacent terms of y-values

d = -5 - 4 = -6,

d = -14 - (-5) = -14+5 = -9

d = -23 - (-14) = -23 + 14 = -9

d = -32 - (-23) = -32 + 23 = -9

It is clear that the common difference between all the adjacent terms is same.

Thus,

d = -9

We know that when y varies directly with x, the function is a linear function.

Here, it is clear that each x value varies 1 unit, and each y value varies -9 units.

i.e. The common difference is same = d = -9

Therefore, the data represent a linear function.

A. The data in the table represent a linear function because there is a common difference of -8.

Step-by-step explanation:

Because I just took the test!

answer:

a

step-by-step explanation:

D

Step-by-step explanation:

A

Step-by-step explanation:

Answer is a because the common difference is -9

The answer is B.

Step-by-step explanation:

The data represent a linear function because there is a common difference of -9.

B) The data represent a linear function because there is a common difference of -9.

Step-by-step explanation:

A linear function is one in which the difference between consecutive y-values is constant. In this table, to get from one y-value to the next we subtract; this means it is a linear function.

Solution:

1. We will plot the points on the coordinate plane, if they lie in a line it means they are linear.

2. Find the slope between each two points ,if you don't want to plot these points on coordinate plane,then by using the formula of slope between two points which is , =[tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex] ,if slopes are same between any two points it means these points are collinear.

As you can see in the coordinate plane that these points are not collinear.

Now , [tex]\frac{y}{x}=\frac{\text{First term}}{\text{Second term}}=\frac{162}{54}=\frac{54}{18}=\frac{18}{6}=\frac{6}{2}=3[/tex]

It means this is a geometric progression because [tex]\frac{\text{Second term}}{\text{First Term}}=\frac{1}{3}[/tex]

Option D : The data represent an exponential function because there is a common ratio of 1/3. is true statement.

D. The data represent an exponential function because there is a common ratio of 1/3.

Step-by-step explanation:

To find a common ratio, find out what the first "y" must be multiplied by to get to the next "y."

162 = 54x

162 ÷ 54 = 3

However, the common ratio is not 3 because the y values are decreasing. The common ratio is 1/3 because 162 × 1/3 = 54.

I hope this helps :))

B

Step-by-step explanation:

Answer is B because it shows a simple difference of -8
