What does the domain refer to?

• The possible x-values of a function.

To check if a parabola is open up or open down what should you be looking at?

• Vertex

• Axis of Symmetry

• Arrows

• Max/Min

What is a vertex?

• Minimum/ Maximum

• Highest/ Lowest Point

• Turning Point

• All of the above

Where is a zero (x-intercept) found on a graph?

• Where the function crosses the y-axis.

• Where the function crosses the x-axis.

• On the top of the graph always.
