The parabola y = ax^2 + bx + c is graphed below. Find a + b + c. (The grid lines are one unit apart.) The parabola passes through (-2,8), (0,0), and (2,8).
There is no parabola shown below, but just from the information that
is provided, an equation that satisfies the three points is y = 2x2.
That would make a + b + c = 2 + 0 + 0 = 2
