Question

How do you find `g(-2)` given `g(x)=-5x+2`?

Answer 1

See the entire solution process below:

Explanation:

To find `g(-2)` substitute `color(red)(-2)` for each occurrence of `color(red)(x)` in `g(x)`:

`g(color(red)(x)) = -5color(red)(x) + 2` becomes:

`g(color(red)(-2)) = (-5 xx color(red)(-2)) + 2`

`g(color(red)(-2)) = 10 + 2`

`g(color(red)(-2)) = 12`
