Answer
Domain: $[0, 5)$
Range: $[-1, 5)$
Work Step by Step
Some important observations about the graph:
(i) The lowest point is at $(0, -1)$.
(ii) The highest point, though it is not really part of the graph since a hole (hollow dot) was used, is at $(5, 5)$.
(iii) The graph is increasing from left to right.
The domain is the set that contains all the x-values of a function.
The x-value of the given function varies from $x=0$ to any number less than $5$ (5 is not included because a hollow dot was used to plot the point (5, 5)).
Thus, the domain of the given function is $[0, 5)$.
The range of a function is the set of y-values.
Notice that the y-values covered by the graph vary from $y=-1$ up to any number less than 5 (5 is not included because a hollow dot was used to plot the point (5, 5)).
Thus, the range of the function is $[-1, 5)$.
