Week 3 Classes of Functions - Subscribe There are many common classes (types) of functions in mathematics: linear, quadratic, trigonometric, rational, and more. Part 1 Choose a class of function (linear, quadratic, trigonometric, rational, etc) and find a 'real-world' example of that function. No more than four students can choose the same type of function (e.g. if four people have already provided examples related to quadratics, you need to find some other function type). Include a reference to the website where you found your information. Part 2 Read through the post of a classmate and visit the website they reference. Post a short reply. Length At least one good paragraph for your original post, and at least a one sentence reply.
