A plumber charges a flat rate of $75 and $30 for each additional hour. The function is y = 30x + 75.
Do the following for this problem:
State the function, real life situation, and define your variables (x and y)
Provide an Input/Output table with 8 values
Graph the function with clearly labeled x- and y-axes.
Find the domain and range
Write a Conclusion

I'm sorry but I need each step done in this problem 1. what is the y variable and what is the x variable? 2. Make an input/output table with 8 values. 3. graph the function with x any axis marked. 4. Find the domain and range. 5. Write a conclusion statement describing what you did. I have no idea how to do these problems. If you can help me, please do each step separately, thank you.
