Let a = 0, and f(x) = (x2 - 3x - 0)/(x2 - 5x + 2). Find lim f(I). Answer: Problem 2 (4 points). Use the Squeeze Theorem to show that lim sin(z) cos Hint: We know that: . lim sinx exists T-40 . cos is always between -1 and 1. Show all of your work! Let a = 5 and f(x) = 2-x*3 - 1.4-x^2 + 5-x + 2. Find lim f(x)
