(b) Find intervals where the function is concave upward or concave downward, and determine any inflection points. (c) Graph the function, considering the domain, critical points, symmetry, relative extrema, regions where the function is increasing or d concave upward or concave downward, intercepts where possible, and asymptotes where applicable. + (a) Find intervals where the function is increasing or decreasing. Select the correct choice below and, if necessary, fill in the answer box OA. The function is decreasing on and increasing nowhere. (Simplify your answer, including any radicals. Use integers or fractions for any numbers in the expression. Use a comma to separ interval notation.) B.
