Some astronauts play baseball on the moon. One of them hits the baseball 2 feet above the ground with an initial vertical velocity of 15 feet per second. The function h = -5t^2 + 15t + 2 represents the height h (in feet) of the baseball after t seconds. Use a graphing
calculator to estimate when the height of the baseball is 11 feet.

I don’t own a graphing calculator so I need help with solving this problem. thank you!!
