Answer 1

D. y = 1.5
`(4)^(x)`

Explanation:

There are a lot of ways to solve this, but here we will just use the simplest way is to put the number in for x and y to see if it is true or not, and that will be the correct answer.

Let's use the point (4, 384)

A. y = 4
`(2)^(x)`

384 = 4
`(2)^(4)`

384 = 64

This is not true, so A is wrong.

B. y = 3
`(2)^(x)`

384 = 3
`(2)^(4)`

384 = 48

This is not true, so B is wrong.

C. y = 4
`(1.5)^(x)`

384 = 4
`(1.5)^(4)`

384 = 20.25

This is not true, so C is wrong.

D. y = 1.5
`(4)^(x)`

384 = 1.5
`(4)^(4)`

384 = 384

This is true, so D is the answer.
