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).    

 

The problem references a graph, but there is no graph provided.    

 

Taking into consideration only the three points that are specified,    

one parabola that goes through those three points is y = 2x² so    

a+b+c for that curve would be 2 + 0 + 0 = 2
