Answer 1

5x-13

Explanation:

combine -2x and 7x to get 5x

and then you are left with 5x -13

Answer 2

Evaluating Functions

Answer:

`f(-3) = -43`

Explanation:

Given:

`f(x) = -x^2 +7x -13`

Solving for
`f(-3)`:

`f(-3) = -(-3)^2 +7(-3) -13 \\ f(-3) = -(9) +7(-3) -13\\ f(-3) = -9 -21 -13 \\ f(-3) = -43`
