Help please I don’t know what to do

Step-by-step explanation:

It ask us to create a exponential function. A exponential function is represented by a equation like this

where a is the vertical stretch, b is the constant rate of growth, and x is the nth exponet.

Using the point 0,2

we can plug that in to find a part of the equation above.

let x=0 and y=2

Let update the equation now since a equal 2

Now let use point 2,8 to find the b value

let x=2 and y=8

Divide both sides by 2

take the sqr root of 4

Let update the equation

answer: .64
