Question

Lori has determined a function f(x) that shows the exponential growth of the number of jeans Tim owns each year. Explain how the f−1(x) can be found and what f−1(250) means.

Answer 1

f^-1 is the inverse of the function

f^-1(250) is to take 250 and substitute it into the inverse function

Answer 2

So I should make a function myself?

Answer 3

Umm, I don't know, it says "Lori has determined a function f(x) that shows the exponential growth of the number of jeans Tim owns each year." So there already is a function.

Answer 4

To find the inverse switch the x's and y's

Solve for Y again, and when you have it to: y = ?

Switch y to \(\ f^{-1}(x)\)


Then plug in 250 into the new function you made by taking the inverse

Answer 5

Okkay thank you ~ I understand now
