Front

Define 'domain' in the context of a function.

Back

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

Front

Define 'range' in the context of a function.

Back

The range is the set of all possible output values (y-values) for a function.

Front

What does it mean for a function to be linear?

Back

A function is linear if it can be graphically represented as a straight line.

Front

What is the slope-intercept form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.
