Question

F(x) = x – 3 PLEASE HELP ME WITH THIS I NEED THE INVERSE OF f(x)

Answer 1

Answer:
`f^-^1(x)=x+3`

Explanation:

f(x)=x-3

use substitution, substitute y for f(x)

y=x-3

interchange x and y

x=y-3

swap the sides of the equation

y-3=x

move the constant to the right-hand side and change its sign

y=x+3

use substitution, substitute
`f^-^1`(x) for y

`f^-^1(x)=x+3`
