思路分析
To determine where a function increases or decreases, we look at the intervals relative to turning points (where the derivative changes sign). The given options suggest a turning point at x = 3, with behavior described for intervals extending to the left and right of 3.
Option A: Increasing: (3, inf)
This states that the function increases strictly to the right of x = 3, starting just after 3. If 3 is a turning point (where the function changes from decreasing to increasing), then the interval of increase would indeed begin after 3.......Login to view full explanation登录即可查看完整答案
