Given,
ƒ(x) = 0 for 0 ≤ x < 4
ƒ(x) = 3 for 4 ≤ x < 8
ƒ(x) = 6 for 8 ≤ x < 12
To select the graph of the given piecewise function.
The solid circle represents the inclusion of the point. Similarly, the hollow circle represents the exclusion of the point.
Option A:
It can be observed in option A that the circles are represented properly and the function is properly shown in the respective interval.
As a result, option A is correct.
Option B:
It can be observed that option B does not follow the proper circle for denoting the endpoints of the interval.
As a result, option B is incorrect.
Option C:
