Lesson 1

Read “In Summary” on page 286 of your textbook for further explanation of how the end behaviour and y-intercept can be determined from the equation of a function.

Then read the following textbook examples before moving on to Self-Check 2.

• “Example 1” on pages 279 to 281 shows how the characteristics of a polynomial function can be predicted from the equation of that function.
• “Example 2” on pages 282 and 283 shows how a function’s equation can be matched to a graph by exploring the characteristics predicted by the equation.
• “Example 3” on pages 284 and 285 shows how to sketch the graph of a function given some characteristics of that function.
