my teacher gave me this q:
a snowball if thrown into the air. The function h= -4.9t^2 + 20t + 1.8 expresses the relationship between height, h, in meters and time, t, in seconds.
a) algebraically determine the max height the snowball reaches
b) how long is the snowball in the air?
i know to solve b you just need to plug in your h and solve for t. however for part a, i am not sure how to solve the max. can someone help?
