Answer:
8
Step-by-step explanation:
RT=10 it is on number A
XY=18 it is on number B
YZ=12 it is on number C
So, I think that no D 8 is in last so that is the answer.
Find the vertex:

Determine if the parabola will open up or down:

Since the value of a is positive, the parabola will open upwards
Find the x and y intercepts:
Factor
to find the x intercepts
(x+8)(x+2)
x + 8 = 0
x = -8
x + 2 = 0
x = -2
x intercepts:
x = -2
x = -8
Find the y intercept

Hence, C. Graph A best represents the quadratic function
