To determine the correct statements about the relative and absolute extrema of the polynomial function h(x), we need to analyze the given grid points.

The grid points provided are:

  • (0, 0)
  • (0.5, 1.75)
  • (2, 0)
  • (3, 3)

Evaluation of Extrema:

  1. At x=0, h(0)=0.
  2. At x=0.5, h(0.5)=1.75.
  3. At x=2, h(2)=0.
  4. At x=3, h(3)=3.

Absolute Extrema:

  • The lowest value occurs at both x=0 and x=2 with h(0)=0 and h(2)=0. Therefore, there is no absolute minimum, as they share the same value.
  • The highest value occurs at x=3 with h(3)=3, so there is an absolute maximum at x=3.

Relative Extrema:

  • At x=0.5, the function increases from (0,0) to (0.5,1.75) and then decreases to (2,0), indicating that this point is a relative maximum.
  • At x=2, it decreases from (0.5,1.75) to (2,0) and then increases to (3,3), indicating that this point is a relative minimum.

Conclusion:

  • There is a relative maximum at x=0.5.
  • There is a relative minimum at x=2.
  • There is an absolute maximum at x=3.

Based on this analysis, the statements Carmen should make include:

  • There is a relative maximum at x=0.5.
  • There is a relative minimum at x=2.

Note that there is no absolute minimum at x=0.5.

Therefore, the correct response for extremum analysis is:

  • There is a relative maximum at x=0.5 and a relative minimum at x=2.
