Скачать или смотреть Composition of functions with two rational functions (fractions) then simplify completely

In this example problem, we are given two rational functions and asked to compose them together. We do so by working from the inside out by first replacing the inner function, then substituting it into the outer function. We then simplify by combining like terms were appropriate, getting rid of fractions within fractions by multiplying numerator and denominator by the same thing and simplifying everything completely.
