Document Summary
Problem 1 solution: calculate each limit below. (a) lim x 7(cid:18) 14. 2 x 7(cid:19) x2 7x . Solution: (a) the least common denominator of the function is x2 7x. Thus, the function can be written as follows: f (x) = Therefore, the limit of f (x) as x 7 is x 7 (cid:18) . 2 x 7(cid:19) = lim x2 7x x(cid:19) = . 7 (b) the function is rational and the degrees of the numerator and denominator are the same. Therefore, the limit of f as x is the ratio of the leading coe cients. lim x . 3: if f (x) = 3x + 1, calculate. Problem 2 solution lim h 0 f (x + h) f (x) h. Solution: it is easiest to calculate the limit by recognizing that, by de nition, Given that f (x) = 2x + 1, we can use the chain rule: lim h 0 f (x + h) f (x) h.
