Respuesta :
The energy usage of a light bulb is a function.
The input for the function is time measured in hours.
The output of the function is energy usage, measured in Kilo watts.
E (energy) is a function of t (time).
The graph of the function will show energy usage on the y axis and time on the x axis.
