Refresher

 

This is a play button that opens Graph.

Use Graph to review how to complete a data table of values and draw a graph for a given function.

Review how to identify domain and range. Work through Concept Development Domain and Range, which offers information, practice questions, and feedback. You will need to click on Domain and Range on two different screens.

Practise identifying the x- and y-intercepts of a graph. An x-intercept of a graph is the x-coordinate of a point where the graph crosses the x-axis. A y-intercept of a graph is the y-coordinate of a point where the graph crosses the y-axis.

This illustration shows a parabola crossing the x-axis at (–2, 0) and (3, 0) and crossing the y-axis at (0, –2). An arrow goes from the label x-intercept to the point (–2, 0) and a second arrow goes from the same label to the point (3, 0). An arrow goes from the label y-intercept to the point (0, –2).

 

Go back to the Are You Ready? section, and try the questions again. If you are still having difficulty, contact your teacher.
