linear function

as x increases, y increases by the same amount each time, a _______ __________ can be written in the form y=mx + b, where m and b are constants and x and y have an exponent of 1. The graph is a straight line.

quadratic function

a function that can be written in the form f(x)=ax^2+bx+c, where a, b & c are real numbers and a is not equal to zero

cubic function

a nonlinear function that can be written in the standard form y = ax^3 + bx^2 + cx + d where a ≠ 0.
