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 are actually multiple parabolas that actually satisfy these conditions.
However, let's set the origin or \((0, 0)\) as the vertex.
This would mean the parabola is facing upwards.
One parabola that wokrs is \(y = 2x^2 \).
If that's the case, then we have \(2+0+0 = 2\) as our answer.
So 2 is our answer, i guess.
Thanks! :)
