To find the domain, we try to visualize all of the $x$-values that are valid inputs for this function. The arrows pointing left and right on the curve indicate that whatever pattern we see in the graph continues off to the left and right. So for $x$-values far to the right or left, we will be able to get an output for $h\text{.}$ The arrows pointing up and down are supposed to indicate that the curve will get closer and closer to the vertical line $x=2$ after the curve leaves the viewing window we are using. So even when $x$ is some number very close to $2\text{,}$ we will be able to get an output for $h\text{.}$ The one $x$-value that doesn’t behave is $x=2\text{.}$ If we tried to use that as an input, there is no point on the graph directly above or below that on the $x$-axis. So the domain is $(-\infty,2)\cup(2,\infty)\text{.}$ To find the range, we try to visualize all of the $y$-values that are possible outputs for this function. Sliding the ink of the curve left/right onto the $y$-axis reveals that $y=0$ is the only $y$-value that we could never obtain as an output. So the range is $(-\infty,0)\cup(0,\infty)\text{.}$
