prob 4

On Exercise 3-4 problem #4 ...If a temperature vs. clock time function is given by y=temperature=T(t), then what is the symbloic expression for each of the following: The temp. at the t=3.... I dont know where to start or what to do...I read the generalized modeling process and I am clueless on what to do. I dont know if I need to pluge into the y=temp.=T(t) or what. I do know that the little t's are given but thats about all I know.

You know that y = T(t).
You don't know the formula for T(t), so the best you can do for t = 3 is substitute 3 for t to get T(3).
If t = (a + b) then T(t) becomes T(a + b).
Whatever t is, that's what you plug in for t.
