Finding Extrema from Graphs


In Exercises 7–10, find the absolute extreme values and where they occur.


Graph showing a line segment from point (2, 0) to point (2, 5) on a coordinate plane, indicating extrema.

검증된 단계별 안내
1
Identify the endpoints of the graph. The graph starts at the point (0, 5) and ends at the point (2, 0).
Determine the type of extrema by analyzing the graph. The graph is a straight line decreasing from (0, 5) to (2, 0).
The absolute maximum value occurs at the highest point on the graph, which is at (0, 5).
The absolute minimum value occurs at the lowest point on the graph, which is at (2, 0).
Verify that there are no other points on the graph that exceed the y-values at the endpoints, confirming the absolute extrema.

Absolute Extrema

Absolute extrema refer to the highest or lowest points on a graph over a given interval. The absolute maximum is the highest point, while the absolute minimum is the lowest. These points can occur at critical points or endpoints of the interval. In the context of the graph, identifying these points involves examining the y-values at the endpoints and any critical points within the interval.

Endpoints of a Graph

Endpoints are the points at the boundaries of a graph's domain. They are crucial when determining absolute extrema, as extrema can occur at these points. In the given graph, the endpoints are at (2, 5) and (2, 0). Evaluating the function's value at these points helps in identifying the absolute maximum and minimum values.

Critical Points

Critical points are where the derivative of a function is zero or undefined, indicating potential local maxima or minima. However, in a linear segment like the one shown, there are no critical points within the interval, as the slope is constant. Thus, for this graph, the focus is on the endpoints to find the absolute extrema.
