The line tangent to the graph of f'(x) at x=0 is vertical and f'(x) is not differentiable at x = 1. Which of the following statements is true? (a) f'(x) does not exist at x = 0. (b) f(x) has a point of inflection at x = 1. (c) f(x) has a local maximum at x = 0. (d) f(x) has a local maximum at x = 1.arrow_forwardball is drawn from one of three urns depending on the outcomeof a roll of a dice. If the dice shows a 1, a ball is drawn from Urn I, whichcontains 2 black balls and 3 white balls. If the dice shows a 2 or 3, a ballis drawn from Urn II, which contains 1 black ball and 3 white balls. Ifthe dice shows a 4, 5, or 6, a ball is drawn from Urn III, which contains1 black ball and 2 white balls. (i) What is the probability to draw a black ball? [7 Marks]Hint.

- Question 2 (3.5 points) A firm produces a certain good. The current unit price of the good is equal to €7. At this price level, the marginal demand is equal to -0.8 and the point elasticity of demand is equal to -0.28. a. Give a precise economic interpretation of the number -0.8. b. Find the exact value of the current revenue of the firm and estimate the change in revenue if the current unit price is reduced by 3%.
