<h2><u><em>A parabola is the graph of a quadratic function. Each parabola has a line of symmetry. Also known as the axis of symmetry, this line divides the parabola into mirror images. The line of symmetry is always a vertical line of the form x = n, where n is a real number.A parabola is the graph of a quadratic function. Each parabola has a line of symmetry. Also known as the axis of symmetry, this line divides the parabola into mirror images. The line of symmetry is always a vertical line of the form x = n, where n is a real number. Before being able to find the equation for the axis of symmetry, let's find the equation of the parabola first. These are the general from of equation for any given parabola: Based on the given graph, the coordinates of the vertex is at (10, 790). Thus, h = 10 and k = 790</em></u></h2>
