Answer
(a) Refer to the image below for the graph.
(b)
domain: $[-2, 5]$
range: $[-4, 3]$
Work Step by Step
(a)
Sketch the graph of the function by creating a table of values.
Plot each point of the table of values then connect them using a line to complete the graph.
Note that the domain is restricted to $-2 \le x \le 5$
(refer to the attached image in the answer part above)
(b)
Use the graph to find the domain and range.
The domain is the set that contains all the x-values covered by the graph/function.
The range is the set that contains all the y-values covered by the graph/function.
Note that:
The domain is restricted to $-2 \le x \le 5$
Thus, the domain is $[-2, 5]$.
The graph covers the y-values from $-4$ to $3$.
Thus, the range is $[-4, 3]$.
