Question

The table of values below represent an exponential function. Find the constant ratio of successive y-values

x values are: -2, -1, 0, 1, 2
y values are: 3, 4.5, 6.75, 10.125, 15.1875


a. 0.5
b. 3
c. 1.33
d. 1.5

Answer 1

I'm not sure but I believe the answer is d. 1.5.
Each y value is exactly 1.5 times greater than the value before.

Answer 2

D. 1.5

Explanation:

We are given the table for the exponential function.

Now, the y-values are given by,

3, 4.5, 6.75, 10.125, 15.1875

To find the ratio of the y-values, we will divide the value by its previous value.

That is, we have,

`(4.5)/(3)=(6.75)/(4.5)=(10.125)/(6.75)=(15.1875)/(10.125)=1.5`

So, we get that,

The ratio of the successive y-values is 1.5.

Hence, option D is correct.
