You can put this solution on YOUR website!
Same as y=4x%5E2%2B5x=x%284x%2B5%29.
Roots are -5%2F4 and 0.
Vertex occurs exactly in the middle of the roots for x, which is at x=-5%2F8. This will be a minimum point for y, because the coefficient on x%5E2 is positive.

The vertex will indicate your range.

Use x=0 to find the y intercept
