Question

Brett has determined a function f(x) that shows the exponential growth of the number of shoes Larae owns each year. Explain how the f^−1(x) can be found and what f^−1(132) means.

Answer 1

f(x) .
f−1(x)
is the inverse function of f(x), it can be found by replacing the x and y values like
if f(x) = x+2
y = x+ 2
inverse is
x = y + 2
x - 2 = y
x-2 = f^-1(x)..

Answer 2

but what values am i supposed to be replacing?
