# Parabolas In Vertex Form

One of the biggest topics in Algebra II is working with different types of functions. From quadratics, cubics, rational, sine and cosine students learn to graph a variety of functions and seeing how each function is effected by parameters. In the sketch below, students work with quadratics that are in vertex form;
$y=a(x-h)^2+k$
Please use the accompanying document with your students to help them understand the relationship of parameters and their effect on vertex form. Students will also learn about the relationship of (h,k) and the vertex along with the Axis of Symmetry.
