(1 point) State the intervals) on which fCa)is increasing. d. (1 point) State the interval(s) on which f(x)is decreasing. e. (1 point) State the interval(s) on which f(x)0 (3 points) List all of the possible rational zeros of -8x2-5x+84 and find therm. 4 ;2, 3, 4,6, 7,12, lt, a, 28, 4 2,84 logs (x-2) (2 points) Determine the domain of g(x) 128 (3 points) Solve 2 x-S

Explanation / Answer

Ans: 1e) [-3, -1.1] U (.5, 2). The points x = -1.1, 0.5, 2 are not included because f (x) = 0 at these points.

1f) (-1.1, 1] U [0, 0.5) U (2, 3) . Same logic as above.
