Question

6. Which function has a horizontal asymptote of y = 3?

a. f(x) = 3(2x)
b. f(x) = 2(4)x–3
c. f(x) = 2(3x)
d. f(x) = 2(4x) + 3

Answer 1

D is the answer f(x) = 2(4^x) + 3

Answer 2

All of those answer choices are linear equations when simplified which don't have asymptotes I believe unless they are in a piece-wise function.

For confirmation, graph them either manually or digitally on a site like Desmos. They are all lines that go on infinitely.
