Question

x f(x)
-1 1
2 3
3 6
5 7
7 8
The values in the table define the function f(x). The value of f^-1(3) is_____________ , and the value of f^-1(8) is____________.

Answer 1

do you know what f^-1(x) means

Answer 2

no

Answer 3

something about inverse functions

Answer 4

For the values given the inverse values are just switched from the original function

Answer 5

Ok - it means the Inverse of f(x)
yes

Answer 6

so its f(x)?

Answer 7

so if you have x = -1 f(x) = 1, you'll have x = 1 f^(-1)(x) = -1

Answer 8

notice how it's just switched around
