Answer: 
Step-by-step explanation:
The measure of the third unknown arc is
.
So, 
The axis of symmetry is given by the line x = a (where a is equivalent to the x-value of the turning point of the parabola) and can be viewed as the line about which the parabola is symmetric; in this case, the parabola has an axis of symmetry of x = 2, thus the answer is B
First, let's expand the right side. Now our equation is

Now, we gather all the terms with x in it on the left side, and the numbers without x on the right. We get:

And then we can make this

We divide both sides by 12 to get x on its own, so x = 13/12 or 1.08
Vertical.
the x value its the same for both, so you are going to the same point before moving up or down for the y value.
The answer is B. y = 0.75 + 2.25. because i've done this assement.
