(a) I have the line plot attached
(b) Purple mean: 30
Red mean: 36

Red median: 36
I'm sorry, that is as much as I can help with, I really am sorry.
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
10^2 since 10(10) = 100 and 10 is multiplied by itself twice.
