3.1H Lesson 1 Key Features of Quadratic Graphs

Labelling

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

Drag labels to their correct position on the image

Zero larger value

Vertex (-4, 2)

Axis of Symmetry: x = -2

Axis of Symmetry: x = 0

Maximum

Vertex (-2, 4)

Axis of Symmetry: x = -4

Minimum

Zero smaller value

Multiple Choice

What would cause the graph of y = x² to open downward?

• multiply the x² by a fraction
• multiply the x² by a decimal
• multiply the x² by a negative number
• multiply the x² by a number greater than 1

Labelling

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

Maximum

Minimum

No zero values

Vertex (2, 5)

Axis of Symmetry: x = 5

Axis of Symmetry: x = 2

Vertex (5, 2)

One zero value

Multiple Choice

What piece of information does h identify in the following equation?
y=a(x-h)²+k

• y value of the vertex
• Axis of Symmetry and the x coordinate of the vertex
• Direction (facing up or down)
• x-intercept
