In order to solve the given problem above, we use

<span>t=<span><span>¬b</span><span>2a</span></span></span>; this would be a much easier method. <span>a=¬16</span> and <span>b=24</span>. We simply plug these values into, followed by simplifying the t value for the time, and then insert this value into <span>h(t)</span> for the height at t. This is one of the ways of determining the maximum of a quadratic function.
