A ball is thrown in the air so that t seconds after it is thrown, its height h (in metres) above the ground is given by h(t) = 25t-5t2
Another ball is fired from a machine, and its height above the ground is given by g(t) = 5+3t, where g is height (in metres) and t is time (in seconds) after it is fired.
(Ignore effects of gravity)
Using the same axes and scales, graph the two functions.
+128408 The domain of the first function is [ 0, 5].....i.e., from the time [ in seconds ] the ball is thrown until it hits the ground
For the second function.....the ball constantly rises......so the domain is [ 0, infinity )
This is, of course, unrealistic.....however....no bounds are specified
