How do you find the turning point of a parabola?

Drawing parabolas
  1. To find the y-intercept, put x = 0 into the equation and work out the y-coordinate.
  2. To find the x-coordinate, put y = 0 in the equation and solve the quadratic equation to get the x-coordinates.
  3. To find the vertex (turning point), add the x-intercepts together and divide by 2.
