6.1 - Exploring the Graphs of Polynomial Functions
This section in an introduction to the graphs of degree 0, 1, 2, and 3 polynomial functions. There is a chart on page 382 of the text that summarizes the material in this section.
If you would like to hear an explanation of the chart please watch the polynomial function video.
Please do 6.1 page 383 #1-4
If you would like to hear an explanation of the chart please watch the polynomial function video.
Please do 6.1 page 383 #1-4
6.2 - Characteristics of the Equations of Polynomial Functions
Standard form for a function is when the terms are in the order of descending degree. When the function is in standard form, it can give you many clues about what the graph would look like.
Please watch the polynomial equations video.

6.3 - Modelling Data with a Line of Best Fit
The line of best fit is used when there is a linear grouping of data on a scatterplot. You can estimate information from the data using the line of best fit.
Please watch the line of best fit video.
Please do 6.3 page 407 #4-8, 10-12.

Please do 6.3 page 407 #4-8, 10-12.
6.4 - Modelling Data with a Curve of Best Fit
When the data on a scatterplot is not linear, then it is sometimes appropriate to use a curve of best fit instead of a line of best fit.
Please watch the curve of best fit video.
