I need to graph the function: Find and show on the graph, the vertex, y-intercept, x-intercept if any, the axis of symmetry. I think I have the answers. I just don't no how to graph it. I believe it's a parabola. The function is f(x)=2x2+4x-30

My answers :

Vertex-1,-32)

y-intercept0,-30)

x-intercept-5,3)

axis of symmetry:-1

Domain:All Real Numbers

Range:[-2,infinity)
