, nd its inverse function f 1(x): give the axis of symmetry for the graph of f (x) = x2 4x. Exam ii, sample d: f 1(x) = x. 1 3x: f 1(x) = 3x, f 1(x) = 1 , f 1(x) = 1 3x x: f 1(x) = 3 + x: if g(x) = 3 x 4, nd its inverse function g 1(x), g 1(x) = x3 + 4, g 1(x) = x1/3, g 1(x) = 3 4 + x, g 1(x) = x. 2: x = 2, x = 1, y = 2, y = 2: let f (x) = x2 3x 4. For what value of x is f (x) minimal: x = 3, x = 4, x , x = 2: which one of the following functions is one-to-one, let f (x) = (x 3)(1 x).
