odule DDA 40 Be sure to show and explain all work. 10 p Part 1 - Exploration Let f (x) = - 30 1+ 2 3 - x a. Use tables and graphs to find lim f(x) and lim f(x) x 7 0o x -> - 00 b. Identify any horizontal asymptotes c. What is the y-intercept? d. How is the numerator of the fraction for f related to part b? e. Sketch the graph. Part 2 - Find the error(s) and solve the problem correctly. Find the derivative, if it exists, of the function at the specified point. f (x) = x '- 4x + 3at x = 1 Answer: f (1) = 1 - 4(1) + 3=0 Part 3 - Discussion
