Question: FEMALE SELF-EMPLOYED WORKFORCE Data show that the number of nonfarm, full-time, self-employed women can be approximated by
N(t) = 0.81t - 1.14√(t) + 1.53 (0 ≤ t ≤ 6)
Where N(t) is measured in millions and t is measured in 5-yr intervals, with t = 0 corresponding to the beginning of 1963. Determine the absolute extrema of the function N on the interval [0, 6]. Interpret your results.
