For this function there are two important intervals: ( - co, A) and (A, co) where the function is not defined at A. Find A For each of the following intervals, tell whether f() is increasing or decreasing. ( - 00, A): Decreasing (A, oo) Decreasing Note that this function has no inflection points, but we can still consider its concavity. For each of the following intervals, tell whether f(a) is concave up or concave down.
