True or False. The two functions f and g defined by
f(x) = 3x + 3 for x real and g(t) = 3t + 3 for t real and positive
are equal?
False. Two functions are equal if their rules are equal and their domains are the same.
True. Functions are equal if their rules are not equal and their domains are different
If functions f and g have domains Df and Dg respectively, then the domain of f / g is given by
the union of Df and Dg
the intersection of Df and Dg
the intersection of Df and Dg without the zeros of function g
None of the above
Let the closed interval [a , b] be the domain of function f. The domain of f(x - 3) is given by
the open interval (a , b)
the closed interval [a , b]
the closed interval [a - 3 , b - 3]
the closed interval [a + 3 , b + 3]
