We are given with the function that expresses the height of the football over time in the equation h (x) = - 16t^2 + 64t. To determine the axis of symmetry, we determine the time when it reaches the maximum height. we derive the equation and equate to zero to get t. - 32t + 64 = 0. t is equal to 2 seconds. Substituting, to the original equation, h (x) is 64. Hence the axis of symmetry is y = 32.
