The vertex of this parabolas is at (2,-4) which of the following could be its equation?

A.

Step-by-step explanation:

Just by looking at the way the graph is pointing you can eliminate answer choices B and C because the set up of this equation will be x = not y =

So the set up of the equation is

x=2(y-(the y value of the vertex)squared+(the x value of the vertex)

by using this you can eliminate option D and see that the answer is A

the answer is 99.

13.46

step-by-step explanation:

16.80 x .20 = 13.46
