Question

What are the approximate values of the minimum and maximum points of f(x) = x^5 − 10x^3 + 9x on [-3,3]?

Answer 1

maximum point: (–2.4, 37.014) and minimum point: (2.4, –37.014)

maximum point: (2.4, –37.014) and minimum point: (–2.4, 37.014)

maximum point: (–1.4, 33.014) and minimum point: (1.4, –33.014)

maximum point: (–3, 30) and minimum point: (3, –30)
