Question

Which function is represented by the graph below?

f(x) = 3x
f(x) = 3x − 3
f(x) = 3x + 3
f(x) = 3^(x + 3)


Question 12

Answer 1

f(x) = 3^x -3

Explanation:

The horizontal asymptote of an unmodified exponential function is y=0. Here, the horizontal asymptote is y=-3, so your answer will be of the form ...

f(x) = [some growing exponential term] -3

Only the second selection has this form. It also matches the given graph at x=1.
