Question

Evaluate the expression when y=-3

Answer 1

Y=-3
subtitute to y^2 + 6y +8
= (-3)^2 + 6(-3) + 8
= 9-18+8
= -1

Answer 2

Answer:

-1

Step-by-step explanation:

Substitute in the known variables:

$y^2 + 6y + 8\\(-3)^2 + 6(-3) + 8$

$-3 * -3 = 9\\(-3)^2 = 9$

$9 + 6(-3) + 8\\9 + (-18) + 8\\9 - 18 + 8$

= -1
