Domain and range word problem

Question

suppose that a ball is dropped from a window that is 64 feet above the ground and that the ball strikes the ground after two seconds. if function h calculates the height of the ball after t seconds, determine a domain and range for h

Answer 1

Your function is height as a function of time... h(t)

 

The domain is all the possible input values of t, time.

Since the ball hits the ground in 2 seconds, the domain is [0, 2]

 

The range is all the possible output values of h, height.

The ball goes from 64 feet to the ground, or zero feet.

The range is  [0, 64]
