Question

If you vertically stretch the exponential function f(x) = 2^x by a factor of 5, what is the equation of the new function?

A. g(x) = 1/5 x 2^x
B. g(x) = 5 x 2^x
C. g(x) = 2 x 5^x
D. g(x) = 2^5x

Answer 1

B

Explanation:

In this case we multiply the function f(x) = 2^x by 5, so the correct answer is B.
