to Crowdmark Section 5. Question 14 (0.00001 points) 1 - 2x Let f (ze) ex/2 (a) Find x-intercepts if there are any. Find intervals when f(x) is positive and intervals when f(x) is negative. (b) Evaluate the limit lim f (ac). (c) Find all critical points of the function y=f(x). (d) Find the intervals of increasing or decreasing. Classify each critical point as local max or local min. (e) Find intervals of concavity and all inflection points. (f) Use the information from previous parts to sketch a graph of the function y=f(x). Clearly label the graph and scale the axes
