Kiernan hits a golf ball off platform. the function h(t)=-16t^2+48x+2 models the height h of the ball above the ground as a function of time t. how long does it take the golf ball to reach its maximum height.

Question

How you'd approach this problem depends upon what course you're in.  I suspect you're in Algebra.  The given equation is that of a quadratic.  Since the max height occurs at the vertex of this upside-down parabola, finding the vertex would be a good and reasonable approach.

If, however, you're in a calculus course, find the derivative of the given function and set it (the derivative) equal to zero.  solve the resulting equation.  The solution will be the time at which the ball reaches its maximum height.
