Quadratic Functions

Quadratic Functions are very important to mathematics and can be used and represented in many different ways. To express functions mathematicians have developed many different forms in which it is easy to distinguish the vertex and axis of symmetry. One of these forms include vertex form or standard form is y=a(x-h)^2+k. This is very helpful when dealing with quadratic equations and parabolas because (h,k) shows the vertex and a is the axis of symmetry. You can also use the descending form as well as the factored form when you are representing a function.When using quadratic equations the vertex form makes plotting points on the Cartesian plane much simpler. When you plot the points that you have gotten from a quadratic equation it will result in a parabola. These parabolas are very interesting because each side of the parabola mirrors the other making the points on the plot symmetrical.  Overall Quadratic functions make up a very important part of math and can be used to do a variety of different things.
