repost of question Second function- with figure
The figure shows the graph of g(x)=e^x and a second exponential function f(x). Identify the second function. My answer was f(x)=2-e^x

Hello, kwtolley!

Identify the second function.

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

$f(x)$ is a vertical reflection of $g(x)$.
Since they have the same y-intercept (0,1),
. . $f(x)$ has the horizontal asymptote $y = 2.$

You are right!
