Use the properties of limits to evaluate the following limits, if the limit exists. . x22x15 a. 11m x>3 x+3 d lim 9x3+7x4 ' xam2x48x2+5 2. Using your graphing calculator and your knowledge of functions and algebra, find all values x = a where the function is discontinuous. For each such x value, evaluate the limit as x approaches a. a. W) = Ix7I x+2 x2+2x b. f(x) = 3. Use the limit definition of the derivative to calculate f'(x) for each function. a. f(x) = 4x2 6x 8 b. f(x) = x 4. Using the result from problem 3b, calculate the equation of the tangent line to the curve at x = 4. 5. The cost to fly x miles on American Airlines could be approximated by the equation 60;) = 0.000003964x+ 191.16. The average cost per mile, denoted by 5(x), is found by dividing C(x) by x.
