Question

Use the graph of f shown in the figure below.

Answer 1

Answer:

  8

Step-by-step explanation:

The attached graph shows the inverse function (red) and the value of the inverse function for an input of -9.

  $f^{-1}(-9)=8$

_____

The inverse function tells you the input required for the given output from the function. So, you can look for an output of -9 on the graph of f and see what input gives that. You find ...

  f(8) = -9

so ...

  f⁻¹(-9) = 8
