Work Step by Step

The inverse of a function differs from the original function in that all the x-coordinates and y-coordinates have been switched. To find the value of $f^{-1}(2)$, we have to find the corresponding x-coordinate to $y=0$ in the original $f(x)$ function.. We can see the graph of $f(x)$ contains $(2, 0)$. Thus, when $y=0$, $x=2$. Therefore $f^{-1}(0)=2$.
