Talib is trying to find the inverse of the function to the right. His work appears beneath it. Is his work correct? Explain your answer. f(x) = -8 x + 4. y = -8 x + 4. y - 4 = -8 x. x = (y - 4) / -8. f^-1 (x) = (y - 4) / -8.

For this case what we are going to do is describe the work part by part:

1) Talib made the correct variable change in the first step.

2) Talib made a correct clearance in the second step by passing the number 4 subtracting.

3) Taliz made a correct clearance in the third step by passing the number -8 dividing.

4) Taliz made an incorrect variable change in the last step.

The correct variable change is:

Error in the last step, the correct solution is:
