Input the data into the calculator or create a data table on . www.desmos.com. Create a scatterplot and determine the best fit model (linear or exponential), then find the regression equation. Use the equation to predict the salary on day 30.
Relate the domain of a function to its graph and, where applicable, to the quantitative relationship it describes. (e.g., if the function h(n) gives the number of person-hours it takes to assemble n engines in a factory, then the positive integers would be an appropriate domain for the function.)
Desmos Graphing Calculator. Kuta Software Algebra II. ... They will collect data and use exponential regression (manually and using technology) to model and analyze the function. They will evaluate the strength of their model and compare their models to peers models.

Provide participants with a copy of the Desmos User Guide. Facilitators may wish to demonstrate the following and ask the following questions, using the Desmos graphing calculator: (Slide 34) Graphing lines (dont need to solve for y) Graphing window in Desmos use wrench icon/drag screen . Label the axes in Desmos
Did the student find the exponential regressions rate of growth or decay. (Find ln(b) and write as percent) Which is it? Growth(b is positive) or Decay(b is negative) Where is the asymptote for the exponential regression? (calculator uses only y=0, but you may want another) What is the end behavior for the exponential?

Researching Regression Analysis.This experiment is a simple example of regression analysis to develop a regression model. Students need to research applications of regression analysis in commercial contexts. Students need to describe 3 examples of applications of regression analysis in their own words.
Students can use graph paper and/or graphing calculators or Desmos. To engage students more effectively in discourse around the lines of best fit, the teacher could use technology (such as ClassPad or Desmos) to show all the different lines of best fit the students have identified layered on the scatterplot.
