Front

Define the term 'range' in the context of functions.

Back

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

Front

What is the definition of a function?

Back

A function is a relation that assigns exactly one output for each input.

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What does it mean for a function to be linear?

Back

A linear function is a function that graphs to a straight line.
