Answer:
top = 17ft
bottom = -12ft
Step-by-step explanation:
As seen in the badly drawn picture attached in this question we are trying to find the point at the top of the ladder and the point at the bottom of the ladder. As seen in the picture ground level has an altitude of 0 ft meaning that lower than this would be in the negatives. Since the basement floor is 12 feet below ground level then this point would be -12 ft. Now since we know that the ladder is 29ft tall we simply add this height to the basement floor value to get the value of the 2nd floor ceiling (top of the ladder).
29ft + ( -12ft) = 17ft
Therefore we can see that the point at the top of the ladder is 17ft.
Given the function

The inverse of the function is calculated by changing f(x) to y and making x the subject of the formula as follows:

We now change back the variables to get the function in the form of inverse function as follows:

Comparing this with Talib's work, we can see that he is correct except for the last line where he did not change the variable y back to x.
Therefore, the last line of his work made his inverse not to be correct.
