Problem 1. Use limits to find the horizontal and vertical asymptotes of f (ac) = 3x2+ 9x 202 - 9 Problem 2. Find the value of c that makes the following functions contin- uous: x -+3x-10 if x * 2 (a) f(2) = 3 if x = 2a - C if x 0 Problem 3. Explain why the equation x7 + x3 - 5x + 2 =0 must have a solution on the interval (0, 1)
