Can you please solve it

10. Can you construct a polynomial function of degree 2 which has no turning points? Why or why not? 11. Can you construct a polynomial function of degree 3 which has exactly one turning point? Why or why not? 12. The product, fg, of two functions, f and 9, whose target is a. subset of the real numbers is dened to be the function (fg)(1:) = f (m)g(s:) if .1: is in the domain of both f and g. Show, if f and g are functions whose domain is the open interval (0, 1), and if f (1:) > D for every x in (0,1), and f and g are increasing on (0,1), then the function fg is increasing on (0,1). 13. Does there exist two increasing functions whose product is not increasing? Explain
