Problem 5

Check if the function f(x)=2x6xf\(\left\)(x\(\right\))=2x\(\sqrt{6-x}\) satisfies the conditions of the following theorem on its domain. If it does, identify the location and the value of the absolute extremum guaranteed by the theorem.
Theorem: Suppose ff is continuous on an interval II that contains exactly one local extremum at cc. If a local maximum occurs at cc, then f(c)f\(\left\)(c\(\right\)) is the absolute maximum of ff on II. If a local minimum occurs at cc, then f(c)f\(\left\)(c\(\right\)) is the absolute minimum of ff on II.
