Question 212614: What is the domain and range of c(g)= 3.03g
Answer by rapaljer(4671)   (Show Source):
You can put this solution on YOUR website! For domain, there are NO RESTRICTIONS on the value of g, so this will allow all real numbers for g. The graph of c(g) then is a straight line with slope of about 3 passing through the origin. The line goes all the way up and all the way down, so the range is (-inf, inf).
Therefore, domain and range are both all real numbers or (-inf, inf).
For an informal explanation of domain and range, see my own website. Do a Bing Search for my last name "Rapalje". Look for "Rapalje Homepage" which should be at the top of the list. Near the top of my Homepage, look for the link "MATH IN LIVING COLOR." Choose "College Algebra", and look in Chapter 2 for the topic "Functions, Domain and Range". This is a free user-friendly explanation, with examples and exercises. The explanation and exercises are given in COLOR, in a way that is much more informal than the traditional textbooks!
