+570 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).
+37147 Vertex (0,0) form of this parabola
y = d ( x-0)^2 + 0
y = dx^2 When 2 Y = 8 So 'd' = 2
then the equation is Y = 2x^2 Then A + b + c = 2
