In a curvilinear relationship, increases in the values of one variable are accompanied by systematic increases and decreases in the values of the other variable. Due of this type of correlation between variables, curvilinear relationship is also called a(n) function. unsystematic construct extraneous nonmonotonic

A non-monotonic function is a function that is increasing and decreasing on different intervals of its domain. As we can see that same thing happens in a curvilinear relationship, that is why it is aslo called a Non-monotonic.
