(-4, 8)

f(-4) = 8 means that if the input of a function is -4 the output is 8, therefore when x = -4, y = 8 and that point lies on the graph.

h(0) = 144 - 16(0)2 h(2) = 144 - 16(2)2

h(0) = 144 - 16(0) h(2) = 144 - 16(4)h(0) = 144 - 0 h(2) = 144 - 64h(0) = 144 The starting height. h(2) = 80 The height after 2 seconds.

h(t) = 144 - 16t2

0 = 144 - 16t2

-144=-144-144 = -16t2

-16 -16

9 = t2

± 3 = t (Reject - 3)

√ √

After 3 seconds the ball will hit the ground.
