Which of the following functions is graphed below? -6 -20 -40 (A) ƒ(x) = –2 (x + 1)² + 5 (B) f(x) = 2(x + 1)² – 5 (C) f(x) = 2 (x – 1)² – 5 (D) ƒ(x) = -2(x – 1)² + 5 %3D - 40. Solve the inequality x2 – 4x – 5 > 0. (A) (-∞, –5] U [1, 00) (C) (-∞, – 1] U [5, 0) (D) (-∞, 1] U [5, ∞0) (B) R 41. Identify the true statement about the given polynomial. f (x) = -8x® – 5.x7 – 4x6 + 2x³ + 5x³ + 7 (A) Number of terms means there at most 6 turning points. (B) Degree means that there are a maximum of 8 zeros. (C) Constant means there are 7 complex zeros. (D) Lead coefficient mans there are exactly 8 maximums.
