Can someone help me to answer this question, please and explain it.

This is calculus 1

4. (20 pts) For f(x) = x3 - 6x2+ 9x -1, Find the intervals, values, and points indicated below. Then graph f. Note: don't worry about the x-intercepts, they are too hard to find. Label the "important points" intercept- INT, local extrema - MAX or MIN, inflection point(s) - IP. Use interval notation for any intervals you have to write. You must show the work to find all the listed values & Intervals or you will receive NO POINTS even if your graph is correct. Domain of f y-Intercept interval(s) where f is increasing Interval(s) where f is decreasing point(s) where a local minimum lies point(s) where a local maximum lies Interval(s) where f is concave up Coordinates of inflection point(s)
