Question

Functions• 3 examples of linear functions:- An equation- A graph- A table• 3 examples of non-linear functions:- An equation- A graph- A table

Answer 1

A linear function is a function with degree 1 (the higher exponent of the variable x is 1). Examples of linear functions are:

equation: y = x + 1

graph of a linear function:

(The equation for this graph is y = 2x + 2)

Table of a linear function:

A non-linear function is any function with degree different from 1.

Examples of non-linear functions:

Equation: y = x² + 2x + 1

graph of a non-linear function:

(the equation for this graph is y = 2x² + x + 1)
