What is the maximum height in a function's context?

Back

The maximum height refers to the highest point on the graph of a function, often found at the vertex of a parabola.

Front

What does it mean if a function is undefined at a certain point?

Back

It means that there is no output for that input, often due to division by zero or taking the square root of a negative number.

What is the difference between a linear function and a quadratic function?

Back

A linear function has a constant rate of change and graphs as a straight line, while a quadratic function has a variable rate of change and graphs as a parabola.

Front

What is the vertex of a parabola?

Back

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

Front

What is the domain of a function?

Back

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