Jaylyn Montes · Answer 1

A. f (x) = 2 (3^x) + 4

Step-by-step explanation:

The linear equations of answer choices B and C will not have a horizontal asymptote. The exponential equation of choice D will have a horizontal asymptote at y=-4.

The appropriate choice is the exponential equation with 4 added:

f (x) = 2 (3^x) + 4
