Written work submission: Taking an online course, it is sometimes difficult to show all the proper work that goes to solve a problem. So we will use this platform to practice showing work of sketching a curve. First, watch 4.5 letture videos posted under Class Notes. Grab a blank piece of paper, and discuss the following function with respect to increasing/decreasing, local max/min, concavity, and inflection points. Then, use the information to sketch the curve. Follow the steps from the lecture video. f(x) 23-322-12x+5
