Question
Last summer, a DAVDECO electrician conducts a record of the electrical voltage supply
readings within 5 hours at a certain locality. (See table below)
Voltage readings (v)
220 v
223 v
0 v
(Power interruption)
221 v
Time (t)
1st hr
2nd hr
3rd hr
4th hr
5th hr
220 v
1. Represent a graph showing the voltage readings as y-values and the time as x-values.
2. Is the graph continuous or not? If your answer is not continuous, at what point or interval
does the discontinuity happen?
Illustrate the graph:
