QUESTION 6 Determine the linear approximation equation for the revenue equation R (x) = 100 2:/x when x = 100. then use it to approximate the number 100+ 2,/ 105- L(X) = 100+ 2\\ 105 is approximately QUESTION 7 The cost equation for a certain product is given by C(x) = 0.1x2 + 1.3x + 4- Find the marginal cost, that is, find the derivative using the limit definition. C'(x) = [M] Note: If necessary, you can write a fraction as A/B and you can write an exponent x2 as x*2. Use parenthesis when appropriate. B
