Graphing Quadratics - Vertex Form

Students reflect on what the vertex represents and write equations for graphed parabolas using transformations of the parent function. Groups then match graphs, vertex form equations, vertex coordinates, axes of symmetry, and range inequalities in a card sort, followed by spiraling practice.

Standards

Common Core

HSF.IF.C.7.A – Graph linear and quadratic functions and show intercepts, maxima, and minima.

TEKS

A.6(A) – determine the domain and range of quadratic functions and represent the domain and range using inequalities
A.7(A) – graph quadratic functions on the coordinate plane and use the graph to identify key attributes, if possible, including x-intercept, y-intercept, zeros, maximum value, minimum values, vertex, and the equation of the axis of symmetry
