Work Step by Step

We are given the function: $h(x)=\sqrt{x+1}$ We start with the basic function $a(x)=\sqrt x$. We horizontally shift $a(x)$ one unit to the left to get $h(x)=\sqrt{x+1}$. We use 3 points: $(-1,0),(0,1),(3,2)$ The domain of $h$ is: $D=[-1,\infty)$ The range of $h$ is: $R=[0,\infty)$
