Question

Given that f(x) is one-to-one, if f(2)=6 and f(3)=7, find:
a) f ^(-1)(6)
b) f ^(-1)(f(3))

Answer 1

were you able to get anywhere?

Answer 2

absolutely not.... I am riding the struggle bus my friend.

Answer 3

f(x) is some function where

you plug in x = 2 and you get y = 6 out

this is because we have f(2) = 6

Answer 4

the inverse simply takes the output and brings you back to the input

it's like a time machine to go back in time

if you know the result (6), then you can use the inverse function to get the original input (2)

Answer 5

does that make sense?

Answer 6

not really... sorry. I just don't understand how to plug it all in and work through it.
