#### Answer

The domain and range of the graph are $\left( -\infty,\infty \right)$, $\left[ -\infty,3 \right)$ respectively.

#### Work Step by Step

We know that the function $f(x)$ is defined for the set of the values of x which is called the domain. The function $f(x)$ is defined for all values of x over the interval $\left( -\infty,\infty \right)$. So, the domain of the graph is $\left( -\infty,\infty \right)$. And the output or the resulting values of the function $f(x)$ are known as the range of the set. The maximum value of the function $f(x)$ is 3, and the minimum value in infinitely low. Therefore, the range of the graph is $\left[ -\infty,3 \right)$. Thus, the domain of the graph is $\left( -\infty,\infty \right)$, and the range of the graph is $\left[ -\infty,3 \right)$.
