Answer: 
Step-by-step explanation:
The quadratic equation in its standard form is:
Now, we are given 5 points of the parabola (if you graph a quadratic equation you will have a parabola), however we only need to choose three points to find the coeficients 
, 
and 
in the quadratic equation.
So, let's choose the first three points:
(-1,14):
(1)
(0,7):
(2)
(1,4):
(3)
Substituting (2) in (1) and (3):
(4)
(5)
At this point we have a system with two equations.
Adding (4) to (5):
(6)
Isolating :
(7)
Substituitng (7) in (3):
(8)
Isolating :
(9)
Now we have the three coeficients and we can write the quadratic equation:
(a+b) + c = a + (b + c)

Answer
Associative property of addition
Answer:
Segment AB || Segment CD
Step-by-step explanation:
Two lines are said to be parallel (||) if they do not meet, even when extended to infinity.
Given: <1 ≅ <3, ΔACD is an isosceles triangle.
Proof: Segment AB || Segment CD
From the diagram given,
AC ≅ AD (side property of isosceles triangle)
<3 = <4 (base angle property of an isosceles triangle)
<1 = <4 (alternate angle property)
Therefore, segment AB is parallel to segment CD.
