1. (a) answer: x = 1 or x = 5 f (x + h) f (x) (b) answer: h. 1 (x + h + 4)(x + 4) (c) answer: g 1(x) = 2x 1 (d) answer: the zeros of h(x) are x = 1 and x = 1. The horizontal asymptote is the line y = 0. 2. (a) hint: the domain of f is {x| 3 x 3}. The domain of g is the set of all x for which. 2 x 6) makes sense. f ( 1 f ( 1. Answer: the domain of g is {x|6 x 18}. 2 x 6) will make sense as long as 3 1. 2 x 6 3. (b) hint: the domain of h is the set of all x for which f (x) is greater than or equal to 0. Answer: the domain of h is {x| 3 x 3. 2 }. (c) answer: a = 1.
