The first graph above is a linear function because its graph is a straight line. function A = s2 giving the area of a square as a function of its side length is not linear because (tables, graphs, and equations). So as you circulate, constantly ask students about the quality of their justifications (MP3). Algebraically, linear functions are polynomials with highest exponent equal to 1 or of the form y = c where c is constant.Nonlinear functions are all other functions.An example of a nonlinear function is y = x^2. representations. Remote Learning Guidance. Solution: Given, 3x+9 = 2x + 18 ⇒ 3x – 2x = 18 – 9 ⇒ x = 9. Regression is a method of estimating the relationship between a response (output) variable and one or more predictor (input) variables. In Lesson 7, students see what examples of linear and nonlinear functions look like as graphs, and in Lesson 8, students will look at examples of functions in all representations and determine if they are linear or nonlinear. Examples; Functions; Apps; Videos; Answers; Main Content.
