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!
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!
