Question

Can someone pleas give me an example of a nonlinear function with 2 inputs? I have to provide 5 problems for class and have no idea where to begin or how to set up the problem.

Answer 1

nonlinear means the exponent on the x variable is not 1. example a parabola like y = x^2 -9 I do not know what you mean by 2 inputs. Inputs are just values of the domain that replace the x and compute the y value at that x point. for y= x^2 -9 inputs {-4, -3, -2, -1, 0, 1, 2, 3, 4} your associated outputs would be range {7, 0, -5, -8, -9, -8, -5, 0, 7} This example is symmetric about the y axis. (it is and even function)
