Can someone please help me with #7, #8, and #9 of the graphing quadratics using -b/2a assignment?

For each polynomial, find the the following features. Then, make a rough sketch based on the vertex, y-intercept, and opening direction. No table needed, this is JUST A SKETCH. Label numbers for the vertex and y intercept. 7) f(x) = 4x2 + 24x + 13 2a Vertex: Axis of Symmetry (AOS): Parabola opens The vertex is a Range: up or down? max or a min? Y-intercept: # of x-intercepts: 8) f(x) = 2x2 - 4x b 2a f (-20) Vertex: Axis of Symmetry (AOS): Parabola opens The vertex is a Range: up or down? max or a min? Y-intercept: # of x-intercepts: 9) f(x) = -2x2 + 4x - 14 b 2a Vertex: Axis of Symmetry (AOS): Parabola opens The vertex is a Range: up or down? max or a min? Y-intercept: # of x-intercepts
