Question

. Which of the following is the maximum value of the equation y = −x2 − x + 6?

Answer 1

x=6-x2-y

Explanation:

Swap sides so that all variable terms are on the left hand side.

add x2 to both side

Subtract 6 from both sides.

Divide both sides by −1.

Dividing by −1 undoes the multiplication by −1.

Divide y+x2 −6 by −1.
