Question

5.

If the parent function is y = 2x, which is the function of the graph?



A. y = 2x − 1 + 2

B. y = 2x + 2 + 1

C. y = 2x − 2 + 1

D. y = 2x + 1 + 2

Answer 1

A. y = 2^x − 1 + 2

Explanation:

Exponential functions have a horizontal asymptote. The equation of the horizontal asymptote is y = 1 .

Horizontal Asymptote:

y = 1
