Question

Help please I don’t know what to do!!!!!

Answer 1

The other person is correct

Answer 2

`y = 2(2) {}^(x)`

Explanation:

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

`y = ab {}^(x)`

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

`2 = ab {}^(0)`

`b {}^(0) = 1`

`2 = a * 1`

`a = 2`

Let update the equation now since a equal 2

`y = 2b {}^(x)`

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

let x=2 and y=8

`8 = 2b {}^(2)`

Divide both sides by 2

`4 = {b}^(2)`

take the sqr root of 4

`b = 2`

Let update the equation

`y = 2(2) {}^(x)`
