Input is time.
Output is measured in kilowatts.
Energy usage measured in kilowatts is a function of time measured in hours.
The graph representing the function will show:
A light bulb as a function expends energy which is measured in kilowatts and it is dependent on time measured in hours.
This implies that, the amount of energy usage of the light bulb is determined by the number of hours the light bulb is turned on.
Thus, energy usage of the light bulb (kilowatts) is a function of time (hours).
Graphing the function, we would plot the input (time) on the x-axis, against (output) energy usage on the y-axis.
Therefore,
Input = time (hours) - plotted on the x-axis.
Output = energy usage (kilowatts) - plotted on the y-axis.
