Question

A volleyball was passed from one player to another with an initial velocity of 28 feet per second from an initial height of 3 feet. The function h(x) = - 16x ^ 2 + 28x + 3mode the height, in , of the volleyball seconds after it was passedWhat was the maximum height the volleyball? A 9 1/3 B 15 C 15 1/4 D 25

Answer 1

C. 15 1/4

Quadratic function have a vertex point that it either there lowest or highest point. In this particular case the vertex point would be (0.875, 15.25) which can be turned into a fraction.
