An object is launched at 13.8 m/s from the ground. The equation for the object's height "h" at time "t" seconds after launch is: h(t) = -4.9t² + 13.8t, where h is in meters.

a. Using the MIN/MAX feature to find the time required for the object to reach it's maximum height. (How do you find it with the features? I know how to use it, but what do you do when you find it?)

b. Maximum height of object? (I got 9.7M)

c. How long is object in air?

RE: I guess you don't really need a graphics calculator. I'm only in Advanced Algebra currently at the moment, and some problems given to us involves some physics and chemistry problems.
