Consider the function f(x) = 8x + 5x-¹. For this function there are four important intervals: (-∞, A], [A, B), (B, C], and [C, ∞o) 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. (-∞0, A): Select an answer C (A, B): Select an answer (B,C): Select an answer (C, ∞) Select an answer C ♥ 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. (-∞0, B): Select an answer (B, ∞): Select an answer
