Quadratic Graph

See how a, b and c shape a parabola. Find the roots, the vertex and the line of symmetry, and check them against the quadratic formula.

What you can do

  • Change a, b and c and watch the parabola move
  • Find the roots, the vertex and the line of symmetry
  • See when there are two, one or no real roots
  • Practice problems with worked answers
