1. The relation that is not a function is y = b. y= a. c. y = v(x – 5) d. x? + y? = 25 2. Given g(x) = x2+ 3x + 1, then a. g(-1) = -3 b. g(-1) = -1 с. g(-1) 3D 5 d. g(-1) = 3 3. The range that best describes the function f(x) = is {f(x) E R/f(x) + 0} b. {f(x) E R/f(x) > 0} a. f(x) E R/f(x) < 0} d. {f(x) € R} C. If f(x) =x- 5, then f="(x) = -x + 5 4. b. f-(x) = -2x + 15 a. 3x+15 2x+15 c. f-(x) = f-(x) = d. 2 3 5. The relation whose inverse is a function is {(1,2), (3,5),(2,5).(-1,3)} b. {(1,7), (2,5),(4,5),(6,1)} a. C. {(4,5), (6,4),(7,2).(3,7)} d. {(1,3), (4,-6),(2,5),(3,5)} 6.
