suppose the function f and g are difined by
f(x) = x^2 + x -2 and g (x) = 1/x
which of the following is/are true?
A. g ( x^2 +3 ) = 1/x^2 + 3
B. f ( 1/x ) = 1/x^2 +x -2
C. (f/g) (x) = x^3 + x^2 -2x and D(f/g) = R
yea. i realize that now. the problem was i was thinking D meant derivative (as it does when programming in maple), so i found it weird when it said D(f/g) = R. but now i realize it is talking about the domain, which makes sense, since there's no way questions of this nature would be asked in a calculus class--unless it's precalculus, in which case, derivatives still wouldn't come up
