Question

Can someone please help me I have tired everything. 

|Let f(x) = x³ – 15x² + 27x + 5. Find the open intervals on which f is increasing (decreasing). Then determine the x-coordinates of all relative maxima (minima). HINT: Use a COMMA between interval answers. Like (2, 4) U [5, ∞) would be "(2,4), [5,inf)" 1. f is increasing on the intervals f is decreasing on the intervals (1,9) (-∞,1),(1,9],(9,∞) 2. 3. The relative maxima of f occur at x = 4. The relative minima of f occur at x = Notes: In the first two, your answer should either be a single interval, such as (0,1), a comma separated list of intervals, such as (-inf, 2), (3,4), or the word "none". In the last two, your answer should be a comma separated list of a values or the word "none".
