Question

The height of a hockey puck that is hit toward a goal is modeled by the function f(x) = −x2 + 8x − 10, where x is the distance from the point of impact. Complete the square to determine the maximum height of the path of the puck. −(x − 4)2 + 26; The maximum height of the puck is 26 feet. −(x − 4)2 + 26; The maximum height of the puck is 4 feet. −(x − 4)2 + 6; The maximum height of the puck is 4 feet. −(x − 4)2 + 6; The maximum height of the puck is 6 feet.

Answer 1

−(x − 4)2 + 6; The maximum height of the puck is 6 feet.
