Math Problem Statement

Identify all of the global and local extrema of the graph.

Solution

To identify the global and local extrema of the graph, let's analyze the given curve:

  1. Local Minimum:

    • The graph reaches its lowest point around (1,0)(1, 0). This is the local minimum because it is the lowest point in a particular interval.
  2. Local Maximum:

    • The graph reaches a peak at two points: one around (4,8)(-4, 8) and the other around (7,19)(7, 19). These are local maxima because they are the highest points in their respective intervals.
  3. Global Minimum:

    • The global minimum of the graph is the same as the local minimum at (1,0)(1, 0), as it is the lowest point on the entire graph.
  4. Global Maximum:

    • The global maximum is at (7,19)(7, 19) since this is the highest point on the graph.

In summary:

  • Global Minimum: (1,0)(1, 0)
  • Global Maximum: (7,19)(7, 19)
  • Local Maximum: (4,8)(-4, 8), (7,19)(7, 19)
  • Local Minimum: (1,0)(1, 0)

Tip: When analyzing extrema on a graph, always check the endpoints and critical points where the derivative is zero or undefined.
