Distinguish between direct and indirect variation. Determine if a given function is direct given a function rule, graph or table of values. Solve word problems related to direct and indirect variation (ref. to regents questions from jmap.org) Distinguish between parallel and perpendicular lines. Do linear regression using a graphing calculator
Activity overview:
Students use a table of sound readings to develop an inverse variation model. After verifying the model, students use it to map safe and unsafe zones based on sound-intensity restrictions. Topic: Rational & Radical Functions & Equations. inverse variation. direct variation…

Students will plot the data points on a graphing calculator. NOTE: Be sure to have some mechanism for students to describe direct square variation as part of the organizing, particularly as it relates to P = I2R. Students will identify the relationship between current and power as a direct square variation and calculate the constant of variation.

Group uses a graphing calculator to graph a direct variation of their choice. Using the table function choose an ordered pair that represents that direct variation. Each group will write this point on the post it poster. Task 2-Group determines the constant of variation (k) for the point. * stress to students that y=kx is the same thing as k=y/x
