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.
2 answers:
To find the inverse of a function, we make the independent variable the subject of the formula.
Thus, the inverse of the given function is evaluated as follows.
From the work show, it can be seen that Talib's work is correct.
Thus, the inverse of the given function is evaluated as follows.
From the work show, it can be seen that Talib's work is correct.
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:
Answer:
Error in the last step, the correct solution is:
