Which is the correct inverse function of f(x) = 4x +9?

Let y = 4x + 9

4x = y - 9

x = (y-9) / 4

f(x) = (x-9) / 4

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are
