Front

What is a function?

Back

A relation that assigns exactly one output for each input.

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.

Front

What is the difference between independent and dependent variables?

Back

Independent variables are inputs (x), while dependent variables are outputs (y) that depend on the inputs.

Front

What is a linear function?

Back

A function that graphs to a straight line, typically in the form f(x) = mx + b.
