+ X m125 - Section 3.9 (2021) - Math VA X Feedback fo webassign.net/web/Student/Assignment-Responses/last?dep=2786834 4 Points] DETAILS One use of linear approximation is to solve certain equations where no algebraic methods apply. This problem illustrates that use. follow the steps below. (a) Find the linearization of e * + x near 0. e 2 + X ~ (b) The equation ex + x = 2 has a solution near x = 0 . To approximate the solution, first create a new equation by replacing the left side of this equation with linearization that you found in part (a). Write this new equation here. Now solve the new equation. X (c) Based on your work above, we can say that the equation ed+ x = 2 has an approximate solution X ~ 8:57 ACTAULC ~ ENG 10/3/ Type here to search+ X m125 - Section 3.9 (2021) - Math webassign.net/web/Student/Assignment-Response [-/1.5 Points] DETAILS (a) Given that f(7) = 18, and f '(7) = -1.3 , estimate f(7.1). Give your answer to two decimal places. f ( 7 . 1 ) ~ (b) Suppose we also know that f "(x) > 0 for all x. Does this make your answer in part (a) an under-estimate or over-estimate? O Under-estimate O Over-estimate 6. [-/3 Points] DETAILS Suppose f'(x) is a differentiable decreasing function for all x. In each of the following pairs, which number is the larger?
