(a) The relationship is curved; as increases, also increases, but at larger values of , increases more rapidly. (b) The relationship is curved; as increases, decreases at first but then starts to increase slowly, but at larger values of , increases more rapidly. (c) The relationship is curved; as increases, increases at first but then starts to decrease slowly, but at larger values of , decreases more rapidly. (d) The relationship is curved; as increases, decreases, but at larger values of , decreases more rapidly.
