Question

Please help me solve this:
What is f-1(f(2))?
f(x)=3/4x-5/6

Answer 1

Is that supposed to be \[\huge f^{-1}\left(f(2)\right)\]

Answer 2

yes

Answer 3

So long as \(f\) has an inverse, then \[\huge f^{-1}\left(f(x)\right)=x\]

In other words, "f inverse evaluated at (f of x) is exactly that value of x."

Answer 4

thank you soooo much!
