## compos′ite func′tion

n. Math.
a function obtained from two given functions, where the range of one function is contained in the domain of the second function, by assigning to an element in the domain of the first function that element in the range of the second function whose inverse image is the image of the element.

For the case where composite function has several intermediate variables, set z = f[u, v, [omega]], u = [phi](t), v = [psi](t), and [omega] = [omega](t) and then get the composite function z = f[[phi](t),[psi](t),[omega](t)].

Results indicate that many of the prospective teachers held historical definitions tied to formulaic rules and that this negatively affected their ability to solve composite function problems.
For example, the previously mentioned composite function would be shown as in figure 5, for which I have introduced letters for variables: x for the original input, n for the output of the first machine and input of the second machine, and y for the output of the second machine.
The deduction of the necessary conditions involves frequent application of the differentiation of the composite functions with respect to time argument and taking the partial derivatives of the differentiated composite function with respect to one of the variables or its derivatives.
