Identify the domain and range of each situation using words and inequalities.
victoria recently switched to a new electric
company. if she uses between 0 and 400
kilowatt-hours (kwh) of electricity per month,
the cost is a set price of $30. if she uses 400
kwh or more per month, the price is $0.097
per kwh.

When x=0 to 400, y=30. This makes ths domain for this inequality 0 to 400 and the range is just 30. When x>400, y=.097x. This makes the domain from 400 to infinity and the range .097(401) to infinity.

Step-by-step explanation:

The price is set between 0 and 400 kWh at $30 dollars flat. The price, however, for any usage of electric greater than 400 kWh is $.097 for every kWh used, making it multiply by the kWh.
