Function notation is a method of writing algebraic variables as functions of other variables. Most often, functions are portrayed as a set of x/y coordinates, with the vertical y-axis serving as a function of x. For exam...

Piecewise functions are solved by graphing the various pieces of the function separately. This is done because a piecewise function acts differently at different sections of the number line based on the x or input value.

Examples of mathematical functions include y = x + 2, f(x) = 2x, and y = 3x - 5. Any mathematical statement that relates an input to one output is a mathematical function. Many simple mathematical functions are written a...
