First we find the vertex of parabola

The vertex of parabola is

Here,
b = coefficient of x term
a = coefficient of x² term
For given parabola, b = 0 , a = -12
So,

And,

Thus the vertex of parabola is (0, 7)
To find another point on parabola, substitute x by 1.

So the second point on parabola is (1,-5)
The plot of parabola is shown in image below:
The correct answer will be 5z^3
the other 2 coordinates are option C
Answer:
Mai was moving faster.
As, she covered a greater distance in the same amount of time.
Step-by-step explanation:
Given: Mai traveled 15 meters in 6 seconds and Priya travels 22 meters in 10 second.
Calculate the speed of both;
Speed defined as the rate at which an object covers distance.

Mai traveled 15 meters in 6 seconds
then;
Speed = 
Priya travels 22 meters in 10 second.
then;
Speed = 
Reason: Mai traveled faster because she covered a greater distance in the same amount of time.
Answer:
The first one, since that is the only one showing in the screen,
and that is actually correct, since there are no intersecting points.
