Please answer it step by step, so I can easily follow it. Please only do 3a, 4def, 5bc

3. Evaluate lim f(x) and lim f(x), using the symbol "co" when appropriate. X-+DO *-00 a. f(x) = 2x + 3 c. f(x) = = 3x + 3x x - 1 2x2 - 5 b. f (x ) = 5x2 - 3 x2 + 2 d. f(x) = 2x5 - 3x 2 + 5 3x4 + 5x - 4 4. For each of the following, check for discontinuities and state the equation of any vertical asymptotes. Conduct a limit test to determine the behaviour of the curve on either side of the asymptote. X x- - x - 6 a. y = x +5 d. y = x - 3 6 b. f(x) = x+2 x - 2 e. f(x) = (x + 3) (x - 1) 1 x2 C. S = f. y = (t - 3)2 x2 - 5. For each of the following, determine the equations of any horizontal asymptotes. Then state whether the curve approaches the asymptote from above or below. X 312 + 4 a. y = c. g(1) = x + 4 12 - 1 3x2 - 8x - 7 b. f(x) = 2x d. y = x2 - 1 x - 4
