Front

What is a function?

Back

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

Front

What does it mean to evaluate a function?

Back

To evaluate a function means to find the output value for a given input.

Front

What is the standard form of a quadratic function?

Back

The standard form is f(x) = ax² + bx + c.

Front

What is the vertex of a parabola?

Back

The vertex is the highest or lowest point of the parabola, depending on its direction.

Front

What is the difference between linear and quadratic functions?

Back

Linear functions have a constant rate of change, while quadratic functions have a variable rate of change.
