Question 96382: I don't understand how you can determine this problem.
its a Qualitative graphing problem. here is the problem
Let F be the temperature (in degrees Fahrenheit) at a specific outdoor location at t hours after 6 A.M. on a specific day. (so t=0 represeents 6 A.M.)
My question: how do you determine the independent from the dependent variable. And how do you know what to put on the graph since there is no numbers. Am I supposed to take my best guess?
I am thinking that the F is dependent and the t is independent. How do I do I graph the problem?
