Question

PLEASE HELP!!!!!

Use the Quadratic model y = -4x^2 - 3× + 4 to predict y if x equals 5.

A. -411

B. -111

C. -89

D. -51

Answer 1

Plug in 5 for x, then simplify:

`y = - 4 {x}^(2) - 3x + 4 \\ y = - 4 {(5)}^(2) - 3(5) + 4 \\ y = - 100 - 15 + 4 \\ y = - 111`

Answer 2

The final answer is B!!!!! :)
