Introduction to quadratic functions

Does this graph in the back have maximum or minimum value?

• maximum
• minimum
• neither
• both

The minimum of a quadratic function is

• The lowest point (vertex) on a graph when a parabola opens up; the point where the graph changes from decreasing to increasing
• The highest point (vertex) on a graph when a parabola opens down; the point where the graph changes from increasing to decreasing

What is the orange line called?

• Line of Solutions

• Roots

• Vertex

• Axis of Symmetry

Does the quadratic have a max/min vertex, and does the parabola open up/down?

• max/ opens down
• min/ opens up
• max/ opens up
• min/ opens down

What is the name of this form:
y = ax² + bx + c

• vertex form
• standard form
• factored form
• zero form

Does the following quadratic equation have a maximum or minimum value? How can you tell?
y=x²+2x-3

• Minimum value, because the a value is positive
• Maximum value, because the b value is positive
• Maximum value, because the a value is positive
• Minimum value, because the c value is negative

What are the x-intercepts?

• 0 and 8

• -2 and -4

• 3 and -1

• 2 and 4
