Evaluate inverse function, the graph of the invertible function h is shown on the grid below what is the value of h^-1(-1)

  h^-1(-1) = 1

Step-by-step explanation:

You are looking for the value of x such that h(x) = -1. Follow the grid line at y=-1 to the right. It meets the graph at x=1.

  h^-1(-1) = 1

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
