Answer: To find the inverse of a function, you need to switch the dependent and independent variables (in this case, m and p) and then solve for the new dependent variable.
Here, the given function is m = p³/90.
Switching m and p, we get:
p = m³/90.
Solving for m in terms of p, we have:
m = ∛(90p).
So the inverse of the function m = p³/90 is m = ∛(90p). This tells us the number of tennis rackets produced (in thousands) given the total number of months.
