1. A ball is thrown into the air with an initial velocity of 22 meters per second.
The quadratic function h(t) = -4.9t2 + 22t + 5.5 represents the height of
the ball above the ground, in meters, with respect to time t, in seconds.
Part A: Determine h(3) and explain what it represents. What is a reasonable domain for the function?

Which expression is equivalent to 3^3 + 2^2?
