Answer:
Option B) is incorrect
Explanation:
Looking at the graph the following points are to be noted.
1) the graph has one maximum and one minimum within the interval.
2)the maximum value is attained at x=8, f(x) = 70
3)The least minimum value attained is at x=0, f(x) = -18
4) the y intercept is attained at x=0, f(x) = -18 ( thus option A is correct)
as the graph decreases then increases within(3,6) and increases then decreases within (1,3) , so options A and D are correct.
And from above option B is wrong
