Problem 2: Find the minimum(s) and maximums of the function f (x) = 3x4 – 6x² + 8 over
the interval [-2,3]
Problem 3. A store owner wishes to create a showroom with area of 200 square feet on three sides.
Find the dimensions that minimize the length of the perimeter.
Problem 4: Find two positive numbers whose product is maximal if the sum of the two numbers
equals 72.
Problem 5: A contractor wants to build a rectangular enclosure. If two sides of the wall cost $12
per linear foot and the other two sides cost $5 per linear foot, then find the minimum cost to
build a 20,000 square feet. Round to the nearest foot.
