Answer
Domain:
$[-1, +\infty)$.
Range:
$[0, +\infty)$
Work Step by Step
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 $[0, +\infty)$.
