Chapter 1 - Section 1.3 - New Functions from Old Functions - 1.3 Exercises: 49


$h(x)=\sqrt x$ $g(x)=x-1$ $f(x)=\sqrt x$

Work Step by Step

Separating the function into three processes: $1. h(x)=\sqrt x$ $2.g(h(x))=g(\sqrt x)=\sqrt x-1=h(x)-1$ $g(x)=x-1$ $3.f(g(h(x)))=f(\sqrt x-1)=\sqrt {\sqrt x-1}=\sqrt {g(h(x))}$ $f(x)=\sqrt x$
