What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

What does it mean for a function to be linear?

Back

A linear function is a function that graphs to a straight line and can be expressed in the form f(x) = mx + b, where m is the slope and b is the y-intercept.
