which might help. It sounds like you have 4 semicircles which can be thought of as a division problem 12/3 = 4. Note how I'm dividing by 3 which is the width of each section (eg: from 6 to 9 is 9-6 = 3 units)
We have the following function: P (m) = m / 6 + 9 Clearing m we have: m = 6 * (p-9) m= 6*p - 6*9 Rewriting: m (p) = 6p-54 Answer: The inverse function for this case is given by: m (p) = 6p-54 option A
