Consider the function f(2) = 6x2 - 624. 1. f is increasing on the intervals 2. f is decreasing on the intervals 3. The relative maxima of f occur at x 4. The relative minima of f occur at x (Round to four decimal places as needed) Notes: Use INF for infinity or - INF for negative infinity. In the last two, your answer should be a comma separated list of a values or the word "none"
