Question

Ialuate the given polynomial for the indicated value of the varl -x^(2)+3x-7, for x=-3

Answer 1

Hello :)

`\mathbb{ANSWER:}`

-25

`\mathbb{STEP-BY-STEP\:EXPLANATION:}`

Our task is to evaluate
`\sf{-x^2+3x-7}` for x = -3.

Substitute -3 for x:

`\sf{-(-3)^2+3(-3)-7}`

`\sf{-9-9-7}`

`\sf{-25}`

Answer 2

- 25

Explanation:

- x² + 3x - 7

substitute x = - 3 into the polynomial and evaluate

= - (- 3)² + 3(- 3) - 7

= - (9) - 9 - 7

= - 9 - 16

= - 25
