WebDec 20, 2024 · In the following exercises, use the limit laws to evaluate each limit. Justify each step by indicating the appropriate limit law (s). 83) lim x → 0(4x2 − 2x + 3) Answer: 84) lim x → 1 x3 + 3x2 + 5 4 − 7x 85) lim x → − 2√x2 − 6x + 3 Answer: 86) lim x → − 1(9x + 1)2 In the following exercises, use direct substitution to evaluate each limit. WebIndeed, in evaluating the limit we only consider what the function does near x = 2, and not what it does at 2. Since the two functions agree near 2, evaluating the limit of one is the same as evaluting the limit of the other. ⁄ (2.3.9) Evaluate limx→2 x2 +x−6 x−2. Solution. We saw above that lim x→2 x2 +x−6 x−2 = lim x→2 (x+3),
