For this activity you will use Geometers Sketchpad to help see what. ħ) To solve f º g (5), input f(g(5)) and press. You can also check that you have the correct inverse function beecause all functions. Ħ) To solve g º f, input g(f(x)) and press. ĥ) To solve f º g, input f(g(x)) and press. Ĥ) To define g(x) = x^2 + 3, input x^2 + 3, press to input the sto → symbol, input g(x) and press. Once this information is entered, a new document will be created. If the user chooses not to save the document, a new document will be created.Ģ) Press or to add the Calculator application to the document.ģ) To define f(x) = 2x - 5, input 2x - 5, press to input the sto → symbol, input f(x) and press. If the user chooses to save the document, the handheld will prompt for a name for the document and the location where the document will be saved. This activity is designed for the students to discover the relationship between the transformtions of a graph and the parameters of the function of the graph. 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. Please Note: If a previous document is already open, the handheld will display Do you want to save 'Unsaved Document'?. To solve composite functions using the TI-Nspire CAS family handheld and computer software, follow the examples below.Įxamples: If f(x) = 2x - 5 and g(x) = x^2+3, find:ġ) Press to create a new document. Composite Inverse Trig Functions Activity Builder by Desmos Loading. How do I solve composite functions using the TI-Nspire CAS handheld and computer software?Ī composite function is defined as using the output of one function (generally f(x)) as input for another function (generally g(x)). An attempt to have my students learn and practice 'nested trig functions' for sin, cos, and tan including inverses.

Solution 27250: Solving Composite Functions Using the TI-Nspire™ CAS Family Handheld and Computer Software. I have adored using the free Desmos Graphing Calculator in my lessons for a few years now, but have only recently discovered the power of Desmos Classroom Activities, which allow students to investigate, and you to monitor, record and facilitate collaboration and discussion.
