A)
y = -16x2 - 51x + 9
B)
y = -0.02x2 + x + 23
C)
y = -10x2 - 0.5x + 8
D)

For larger x, the value of the squared term will be more significant than the other terms, so you can estimate it in your head. Look at x = 10 for easy numbers.

Do they have this software for mac?

I usually use MATLAB to graph stuff. It's definitely not optimal.
