Which system models the height of the tennis ball and the height of the dog's mouth over time? h = 4. 5t 18 and h = -16t2 1. 5t 21 h = 18t 4. 5 and h =-16t2 21t 1. 5 h = -16t2 4. 5t 18 and h = -16t2 1. 5t 14 h = -16t2 18t 4. 5 and h = -16t2 21t 1. 5.

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
