Question

How do you find the inverse of `g(x)=x-2`?

Answer 1

`g(x)=x+2`

Explanation:

`g(x)=x-2` To find the inverse of an equation, switch the `y` (`g(x)` in this case) and the `x`.
`x=g(x)-2` Now, solve for `g(x)`
`g(x)=x+2`

Note this is my vague recollection of Algebra II knowledge, not sure if it necessarily applies to Precalculus....
