The document outlines assignments and lessons for math class, including a test review and test scheduled for the next day. It provides warm-up problems on areas and circumferences of circles, scientific notation, and simplifying expressions. The main lesson defines linear and proportional functions, and gives examples of making function tables and graphs for various linear and non-linear functions.

Lesson 41:
*function – a mathematical rule that identifies a
relationship between 2 sets of numbers; for each input there
is only one output
*linear function – if all the input­output pairs of a function
fall on a line
*For a graph to be proportional, it must be:
­linear,
­­pass through (0, 0),
­­­and rises to the right
