Composite functions desmos activity10/11/2023 Hopefully a real world example will help students see the relevance, spur discussions on when you may want to subtract functions or multiply or divide them, and give them insights into tasks financial analysts may perform in their daily work. To see the data on Desmos’ site, click the image below. Graphing that line as well helps build a case as to whether or not Apple should be worried about the iPhone cannibalizing iPod sales. I would like to compose four functions and graph it. Two equations can be found that model the data.Īgain, should Apple be worried. Hopefully this brings a discussion about how graphs can skew perception based on scale.Īsk students to add the functions to get a combined units sold. Getting up to speed calculating the graph of an inverse function and understanding the properties of its graph. ![]() We offer Integrated Computing for Algebra, Physics and Data Science, for all students. This activity was created by the Bootstrap team. Includes text, scale, rotate, flip-horizontal, and flip-vertical. It then practices finding inverses and graphing inverses. When the data is entered into the Desmos online calculator, a linear regression can be performed. Students match images to code using Pyret syntax for Bootstrap. This exploration with composing functions leads students to the concept of inverse functions by noticing that for some functions f(g(x))g(f(x)) and that the line yx is produced by each composition. It is apparent that iPhone sales are cannibalizing iPod sales. Little is done to describe when this might actually be used or applied.Īccording to, Apple’s iPhone fiscal sales are steadily climbing.ĭuring the same time frame, iPod sales are steadily falling. Then they are introduced to composite functions. Then two functions are given and students are asked to add them, subtract them, multiply them, and divide them.
