Answer

True statement

Work Step by Step

The graph of a quadratic function is parabolic (U-shaped), so either the graph opens up or opens down. If the graph opens up, then the quadratic function has a minimum value, and if the graph opens down, then the quadratic function has a maximum value. Thus, it is clear that every quadratic function has either a maximum value or a minimum value.
