Find (a) the domain of f, (b) the critical number(s), and (c) interval(s) where the function is increasing and decreasing. If there is more than one number or interval, separate answers with a semicolon. Type -INF for- and INF for. Responses must contain a simplified fraction, a/b, when necessary. Do not enter any spaces in your answers. You may use the quadratic formula where necessary. In part (c), use a sign chart, and do not use brackets in your answer: Letf(x)=3/42-5/3+2-2 +2 (a) The domain off (in interval notation): (b) Critical number(s): x= (c) Interval(s) where the function is increasing: Interval(s) where the function is decreasing:
