Question

The graph of the invertible function g is shown on the grid below. What is the value of g^-1(-8)

Answer 1

Answer:  7

=======================================================

Explanation:

The result of $g^{-1}(-8)$ is the same as trying to find x in $g(x) = -8$

Draw a horizontal line through -8 on the y axis. This horizontal line intersects the curve at point P. From point P, move upward until you reach the x axis. You should get to 7 on the x axis. Therefore, the solution to $g(x) = -8$ is $x = 7$. In other words, $g(7) = -8$. This ultimately means $g^{-1}(-8) = 7$

Refer to the diagram below.

Answer 2

Answer:

-7

Step-by-step explanation:

the variable is g and all you have to do is subtract -8 by 1 to get -7
