Answer:  Period = 4

               Amplitude = 3

<u>Step-by-step explanation:</u>

Period is the interval of one "cycle" before the pattern repeats.

If you notice that when x = 0, y = -4.  

When does the pattern repeat (reach -4 again)?

Answer: when x = 4.

So the interval of one "cycle" is 4 units -->  Period = 4.

Amplitude=\dfrac{Max-Min}{2}=\dfrac{2-(-4)}{2}=\dfrac{6}{2}=\bold{\large\boxed{3}}

Step-by-step explanation:

Hi, to answer this question we have to substitute h=0 (when the rock hits the ground the height above it is 0) in the equation given:

h (t) = –16t2 + 20

Solving for t (time)

0= –16t2 + 20

16t2=20

t2=20/16

t=√1.25 =1.12 seconds (option C)
