Equation Editor Find the critical points and the intervals on which the function is increasing or decreasing, and apply the First Derivative Test to each critical point. f(x) = -6 tan -1 x + 3x + 1 on the interval (- infinity, infinty ) (Use symbolic notation and fractions where needed.) Left critical point = is: a local maximum a local minimum neither maximum nor minimum (Inflection point) Right critical point = is: a local minimum a local maximum neither maximum nor minimum (Inflection point)

Explanation / Answer

Left critical point = -1. is local max

Right critical point = 1. is local min
