For a complete lesson on parabola equations and graphing parabolas, go to http://www.yourteacher.com  1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn to graph quadratic equations that are written in y  k = a(x  h)2 form by using the coordinates (h, k) to graph the vertex, and using the x and yintercepts to graph the parabola. Students are reminded that to find the yintercept, they must substitute a 0 in for x, and to find the xintercept(s), they must substitute a zero in for y. Students are also asked to find the axis of symmetry using the formula x = h.

What does it mean to write the equation of a parabola in vertex form when the vertex and points are given? Ex. vertex{3,4} point{2.5}
Great Question! There are different ways to write out the equation of a parabola and these ways will depend on the pieces of information provided. In this case the vertex point is given and then a separate point on the ...
