Front

What is the domain of the function f(x) = 1/x?

Back

All real numbers except x = 0.

Front

What does it mean for a function to be continuous?

Back

A function is continuous if there are no breaks, jumps, or holes in its graph.

Front

What is the difference between a function and a relation?

Back

A function is a specific type of relation where each input has exactly one output.

Front

What is the vertical line test?

Back

A method to determine if a curve is a function by checking if any vertical line intersects the curve more than once.
