Hi, everybody. We're going to do Section 4.8, Number six where they tell you that F of X is equal to four X. And then the question they want to know is, what is I of f of two? So this is a composition of function. So whenever we compose functions, we always work from the inside out. So let's start on the inside and find f of two. Well, they again. They told us that F of X is for X, so f of two says replace the X value is too, so it would be four times to which is eight. So we just found out that effort to is eight. And what will I of eight be? That's the question. Well, I is. The identity function on the identity function is when y is equal to x. Your influence the same as your output. So if your input is eight, your output would also be eight. So the answer is eight
