Domain: $[-1, +\infty)$. Range: $[0, +\infty)$
Some important observations about the graph: (i) The lowest point is at $(-1, 0)$. (ii) The graph is increasing from left to right (without a bound on the right). The domain is the set that contains all the x-values of a function. The x-values included in the given function are all the real numbers greater than or equal to $-1$. Thus, the domain of the given function is $[-1, +\infty)$. The range of a function is the set of y-values. Notice that the y-values included in the graph of the function are all real numbers greater than or equal to $0$. Thus, the range of the function is $[0, +\infty)$.
