Identifying Key Features of Quadratics Graphs

Label the graph. Match the zero smaller and larger values by placing the box on the graph next to what it represents.

e

a

f

g

h

Maximum

Axis of Symmetry: x = -4

Axis of Symmetry: x = 5

Zero larger value

Vertex (5, -4)

Minimum

Zero smaller value

Vertex (4, -5)
