Advanced Math practice question

Answer: 8

The squared term is at most 0 (at x = −1) because of the negative sign, so the maximum value is 8.

Common wrong answers

If you answered 7

7 is f(0), the y-intercept; the peak sits at x = −1 with value 8.

If you answered -1

−1 is the x-location of the peak; the maximum VALUE is 8.

If you answered -8

The negative sign flips the parabola, making +8 the top, not the bottom.
