Consider the function f(x) = 3x + 8x-1. For this function there are four important intervals: (-∞o, A], [A, B), (B, C], and [C, oo) where A, and C are the critical numbers and the function is not defined at B. Find A and B and C For each of the following open intervals, tell whether f(x) is increasing or decreasing. (-∞o, A): Increasing (A, B): Decreasing (B, C): Decreasing (C, ∞) Increasing Note that this function has no inflection points, but we can still consider its concavity. For each of the following intervals, tell whether f(x) is concave up or concave down. (-∞o, B): Concave Down (B, ∞o): Concave Up Question Help: Video OT
