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.

@FutureMathProfessor plss help meee

shamil98 · Answer

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)

shamil98 · Answer

replacing the values and then solving for y*

anonymous · Answer

then what would be next?

shamil98 · Answer

f^{-1)(132) you input 132 into the x value(s) of the inverse function and evaluate it.
then you would plot the points on a graph where x is 132 and y is the result of 132 input in the function
