By definition, nonlinear functions are functions which are not linear. The process of linearization, in mathematics, refers to the process of finding a linear approximation of a nonlinear function at a given point (x 0, y 0). A nonlinear function is--like the name suggests--a function that is not linear. This activity extends students' thinking of graphs of common functions to thinking of them as parts of a larger function. Just like with equations, when the exponent of the variable x is not equal to 1, then the equation is non-linear; therefore, the function described by a non-linear equation will graph as some kind of curve, i.e., not a line.
