We suggest that you first use an analytical method to find the equation of the parabola and then use the applet to change h, k and a to solve the same question graphically. ... 5 - Example: A parabola has a vertex at (-1,2) and passes through the point (1,-2). Find an equation to this parabola of the form y = a(x - h)2 + k.

6. The graph of a quadratic function is symmetric with respect to a vertical line containing the vertex. This line is called the axis of symmetry. If (h, k) is the vertex of a parabola, then the equation of the axis of symmetry is x = h. ... To find the x-intercept, we solve the equation, -2(x – 3) + 2 = 0...
