Which point(s) are on the graph of the following parametric equations? x(t)=2t y(t)=t^2 a.) (-4,4) b.) (-2,-4) c.) (0,0) d.) (1,2) e.) (6,9) there should be 3 of these that are right

x(t)=2t
y(t)=t^2
A) (-4,4),
x(t)=2t=-4, t=-2
y(-2)=(-2)²=4 , True

B) (-2,-4)
x(t)=2t=-2, t=-1
y(-1)=(-1)²=1 False. we have y=-4 

C) (0,0)
x(t)=2t=0, t=0
y(0)=(0)²=0   True 

D)(1,2)
x(t)=2t=1, t=1/2
y(1/2)=(1/2)²=1/4 False. we have y=2

E) (6,9)
(-2,-4)
x(t)=2t=6, t=3
y(3)=(3)²=9 True.     

Correct answers is A, C, E.
