PLEASE HURRY Review the graph of . On a coordinate plane, a parabola opens to the right. It goes through (0, 8), has a vertex at (negative 3.5, 2), and goes through (0, negative 4). Everything to the left is shaded. Which justification can be used to demonstrate the graph is correct? Boundary values are included as part of the solution set. The positive coefficient StartFraction 1 Over 10 EndFraction indicates the parabola opens up. The coefficient of the y2 term is a fraction, so the parabola opens to the right. Shading is to the left because (0, 0) does not satisfy the inequality.
