Expert Solution
Step 1

We know that if f(x) is a linear function , then inverse function of f(x) is also linear , so graph of inverse function of f(x) is also a line.

Also we know if f(x)=y then f^-1(y)=x

Step 2

From graph , we find values of y=f(x) for different values of x , then values of f^-1(y)

f(-5)=-4 4)= -5
f(-4) -2 (-2)=-4
f(-3) 0()-3
f(-2) 2 (2) = -2
f(-1) 4 (4)=-1
f (0) 6(6)0
f(1)8 (8)1
f(2)10 (10)-2
