101. For all x real, √(x² -4x + 4) = A) x - 2 C) |x - 21 102. The value of x that makes x2 + 6x + 13 minimum is equal to A) 6 C) 13 03. eln(3)-In(2) + In(1/x) = B) x + 2x + 2 D) x + 2 B) -3 D) 3 B) 3x/2 D) 3/2 - 1/x A) 3 / (2x) C) 1 + 1/x 04. If f(x) = (x - 1)/(x + 2), then the range of f is given by the interval A) (-∞, -2)U(-2, +00) B) (-0, 1)U(1, +00)

C) (-2, +∞0) 105. In((x - 1)²) = 2 In(x - 1) for all x in the interval A) (-∞0, +∞0) C) (-∞0, 1)U(1, +00) 106. Let f(x) D) (-00, 1) A) f(x) has a maximum value C) The graph of f has no x-intercepts. B) [0, +00) D) (1, +00) = x² + 2x + 4. Which of the following statements is NOT true? Ans: Ans. B) The graph of f is not a line D) The graph of f has a y-intercept. Ar
