## Algebra 2 (Class 83)

Lesson Title
4.3.1 How can I write it in graphing form?

Overview
In Lesson 4.1.3 students found that one way to change the equation of a parabola form the standard form f(x)=ax^2+bx+c to graphing form f(x) = a(x-h)^2+k is to find the vertex and then substitute coordinates of the vertex for h and k. But how can you find the graphing form for an equation like x^2+4x+y^2+2y=11? In this lesson and the next students will learn a new method for doing just that!
