A linear function is a function which gives a Straight line.
Algebraically y = mx + c is a linear function. because for every 'x' put in, you only get 'one  y ' as a answer.
However, x^2, x^3 etc. are nonlinear functions because when inserting different 'x' you may arrive at the same answer.
e.g.
y = x^2
When x = 2
y = 4
When x = 2
y = 4 The same answer. !!!!
Any graph that is NOT a straight line is a nonlinear function.
