Find the open intervals where the function is increasing and the intervals where the function is decreasing. Determine the relative extrema of the function. f(x) = x³5x² + 8x 2. According to the Florida Agency for Workforce, the monthly average number of unemployment claims in a certain county is given by N(t) = 22.16t2 - 238.5t + 2005, where t is the number of years after 1990. a) During what years did the number of claims decrease? b) Find the relative extrema and interpret it. 3.
