Find the domain and range of each function. y = log(x + 1)

An electric utility charges residential customers a $\$6$ monthly fee plus $\$0.04$ per kilowatt hour (kWh) for the first 500 kWh and $\$0.08$/kWh for usage over 500 kWh. Write a piecewise function $f(x)$ that can be used to determine a customer’s monthly bill for using x kWh of electricity. Graph the piecewise function. A customer uses 613 kWh of electricity in one month. How much should the utility charge the customer? Explain how you determined your answer
