Use interval notation to write the intervals over which \( f \) is (a) increasing. (b) decreasing, and (c) constant. Part 1 of 3 The function is never increasing. The tunction is sometimes increasing. increasing interval: The function is always increasing. Increbsing inserval: The function is always incressing. Increasing intervalt Part 2 of 3 The function is never decreasing The function is sometimes decreasing. Decreasing incerval: The function is always decreasing. Decreasing interval: Part 3 of 3 The function is never comstant. The function is sometimes constant Constant interval: The function is slways constant. Coristant intervalt The function is never increasing. The function is sometimes increasing Increasing interval: The function is always incressing: Iffereacind interval: The function is never decreasing. The function is sometimes decreasing. Decreasing interval: The function is always decreasing. Decreasing interval: Part 3 of 3 The function is never constant. The function is sometimes constant. Constant interval: The function is always constant. Constant intervalt
