Domain function help?

How to find the domain and range and graph this function? I need help asap?

  • You are designing a poster. The poster is 24 in. wide by 36 in. tall. On this poster you want to place a square photograph and some printing. If each side of the photograph is x in., the function y=864-x^2 gives the area of the poster available for printing. a. Graph the function. b. What values makes sense for domain? explain why. c. What values make sense for the range? explain why. please explain how to find the domain, range and how to graph it. thanks so much

  • Answer:

    The domain is always the possible input values for the x variable. And the range is always the possible output values for the y variable. Graphing it is hard to explain but a simple process. I suggest googling " how to graph functions" hope this helped. Oh and if you have a textbook for this class which I assume Is Algerbra then go to your index and find graphing functions. Good luck Sasha!
