Question

Let f (x) = 8^x

Which function represents a transformation of
F(x) by a vertical stretch with factor 2?
g (x) = 1/2 • 8^x
g(x) = 81/2^x
g (x) = 8^2x
g(x) =2 • 8^x

Answer 1

:

The answer is g (x)=2(8)^x

Explanation:

this is the answer

Answer 2

Answer: D. 2(8^x)

How:
Since you are looking for a vertical STRETCH, you would mail toy the entire function. And since we have the given factor of 2, we would use this to multiply the entire function of f(x)=8^x.

Therefore we get the finalized answer of 2(8^x) or your fourth option
