Question

Choose all of the following equations that have a vertex that is the maximum point of the parabola. More than one answer may be chosen. y = −4x2 + 8x − 19 y = −x2 − 7x + 1 y = 8x2 − 6x + 128 y = 3x2 + 9x − 4

Answer 1

Parabolas have a maximum when it opens downward. Parabolas open downward when the equation is \(y = -ax^{2} + bx + c.\) Pick the ones that have a -a.
