Create a quadratic equation for the given problem and then solve the equation with a related function using a graphing calculator. If necessary, round your answer to the nearest hundredth.

A bird is in a tree 42 feet off the ground and drops a twig that lands on a rosebush 38 feet below. The function h(t) = −16t2 + 42, where t represents the time in seconds, h gives the height, in feet, of the twig above the ground as it falls. When will the twig land on the bush?

The twig will hit the rosebush after about
second(s).
