Answer
Refer to the attached image for the graph of the given function
Work Step by Step
To graph the given function, perform the following steps:
(i) Create a table of values by setting x=0, 1, 2, 3, and 4 then solving for C(x) (or the y-value) of each one.
Note that the the value of x cannot be negative as it represents number of hours.
Similarly, $C(x) cannot be negative as it represent cost.
(Refer to the attached image below for the table of values)
(ii)Plot each ordered pair (or points) on the same coordinate plane, then connect the points using a straight line. (Refer to the attached image in the answer part).
