Question

1. the complete set of all possible output values (y-values) that a function can produce is known as the range.2. the highest or lowest point on the graph of a quadratic function, depending on whether it opens upwards or downwards, is called the ____.3. if the parabola of a quadratic function opens upwards, the vertex represents the __ value of the range.4. if the parabola of a quadratic function opens downwards, the vertex represents the ____ value of the range.

Explanation:

1. The key point of a quadratic function's parabola (the highest or lowest point) is defined by this term.
2. An upward-opening parabola has a vertex that is the minimum point, so its y-value is the start of the range (the smallest output).
3. A downward-opening parabola has a vertex that is the maximum point, so its y-value is the largest output in the range.

Answer:

1. vertex
2. minimum
3. maximum
