Evaluate 1-5

A. Evaluate the limits for each of the following: [5 points each] 1. lim (x2+2x - 4)/(x + 2) x - 1 2. lim (x + 3)/(x -2) x -+ 2 3. lim (x2 - 7x + 10)/(x2- 5x + 6) x -+ 2 4. f(x) = {x + 1, x 1 [consider this to be a split function] Then evaluate f(x) as x - 1 5. Given the following information, sketch a graph for a smooth, continuous function unless otherwise indicated. f(1) = 2 and lim as x - 5 for f(x) = 3 and oscillates at x = 0 and lim f(x) = -3 as x -> -2+and lim f(x) = 3 as x - -2
