11) Review: The height in feet of a projectile with an initial velocity of 120 feet per second and an initial height of 140 feet is a function of time in seconds given by h(t) = â16t2 + 120t + 140. What is the maximum height obtained? What is the height after 2 seconds? Hint: Since the graph is an upside-down parabola, the maximum occurs at the vertex. So use the vertex shortcut formula -b/(2a) to find t and plug that t-value into the function. For the second question you are evaluating the function at a given t-value.
