SOLUTION: If a baseball is projected upward from the ground level with an initial velocity of 64 feet per second, then its height is a function of time, geven by s(t) = - 16t^2 + 64t. Graph

Question 21207: If a baseball is projected upward from the ground level with an initial velocity of 64 feet per second, then its height is a function of time, geven by s(t) = - 16t^2 + 64t. Graph this function for 0 < t < 4. what is the maximum height reached by the ball?

Solved by pluggable solver: SOLVE quadratic equation (work shown, graph etc)

Quadratic equation (in our case ) has the following solutons:

For these solutions to exist, the discriminant should not be a negative number.

First, we need to compute the discriminant : .

Discriminant d=4096 is greater than zero. That means that there are two solutions: .

Quadratic expression can be factored:

Again, the answer is: 0, 1. Here's your graph:
