Hello, kwtolley!

Quote:

The figure shows the graph of $\displaystyle g(x)=e^x$ and a second exponential function $\displaystyle f(x)$

Identify the second function.

My answer was: $\displaystyle f(x)\:=\:2-e^x$

$\displaystyle f(x)$ is a vertical reflection of $\displaystyle g(x)$.

Since they have the same y-intercept (0,1),

. . $\displaystyle f(x)$ has the horizontal asymptote $\displaystyle y = 2.$

*You are right!*
