Section II: [6 marks] Tangent Line Write detailed solutions on exam paper and submit copies of your written solutions to Crowdmark Section 2. Question 11 (0.00001 points) Consider the family of functions y - f() = x - k In(2 ), where k _ Lisa constant number. (a) Find the equation of the tangent line of y=f(x) at x = a (b) Determine the value ac - a such that the tangent line above passes through the origin (0,0). (c) Does your answer in part (b) depend on the parameter k? Write one or two sentences describing your observation for this family of functions. (d) Give the equation of the tangent line in part (b) in slope-intercept (i.e., y=mx+b) form. I will upload my answer document to Crowdmark at the end of the exam supervised by the Examity proctor. evious Page Next Page Page 6 of 12 Submit Quiz 0 of 17 questions saved
