Vertex Form
Date: _____________ Block: ___________
Read all directions CAREFULLY!
Convert each equation to vertex form. Use vertex form to find the vertex, direction, domain, range, and
the axis of symmetry. State whether the graph will have a maximum or minimum. Then graph each
equation.
1. y  x 2  4 x  1
2. y   x 2  4 x  2
