Question

The energy usage of a light bulb is a function. The input for the function is _________, measured in hours. The output of the function is energy usage, measured in ____________. Identify the functional relationship between the variables. _________________ is a function of _________________. The graph of the function will show energy usage on the _____________ axis and time on the _______________ axis.

Answer 1

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.
