Work Step by Step
Looking at the graphs, we find that as $x$ approaches $0$, the functions $f(x)=x$ (the red graph)and $g(x)= \sin x$ (the blue graph) approach approximately the same values. So, the function $h(x)=\frac{g(x)}{f(x)}= \frac{ \sin x }{x}$ (the green graph) must approach $1$ when $x$ approaches $0$, as confirmed by the graph. Thus, we can conclude that$$\lim_{x \to 0} h(x)=1.$$
