Front

What is the definition of a piecewise function?

Back

A piecewise function is a function defined by multiple sub-functions, each applying to a certain interval of the domain.

Front

What is the significance of the vertex in a quadratic function?

Back

The vertex represents the maximum or minimum point of the parabola, depending on its orientation.

Front

How do you determine the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) that will not cause any undefined behavior.

Front

What does the absolute value function represent graphically?

Back

The absolute value function reflects all negative values of x to positive values, creating a V-shaped graph.
