May and Richard are throwing a Frisbee at the beach. When May throws to Richard, the height, in metres, of the Frisbee above the sand after t seconds is described by the function
h(t) = -2t²+3t+1.
a.) Find the avg. velocity of the Frisbee for the time period beginning when t=1 and lasting
i.) 1 s ii.) 0.5 s
b.) Find the instantaneous velocity of the Frisbee when t=1

Easiest and no brainer(don't try it on tests because your teacher will take off points) graph it.

v = dh/dt = -4t+3
Avg V starting at t =1 and ending at t =2 is:
((-4*2 + 3) - (-4*1+3))/(2-1) = -2
Avg V starting at t =1 and ending at t = 1.5 is:
((-4*2+3)-(-4*1.5 +3))/(1.5-.5) = -4
Instantaneous V at t =1 is (-4*2+3) = -5
