(Hint: Complete the square.) 27-32. Graphing inverse functions Find the inverse function (on the given interval, if specified) and graph both f and fon the same set of axes. Check your work by looking for the required symmetry in the graphs. 27. f(x) = 8 - 4x 28. f(x) = 3x + 5 29. f(x) = Vx + 2, for x 2 -2 30. f(x) = V3 - x, for x - 3 31. f(x) = (x - 2)2 - 1, for x 2 2 32. f(x) = x2 + 4, for x 2 0
