The age of a black walnut tree can be calculated based on the diameter of the trunk, according to the following function A=1.8d ±2 years, where A is the age in years and d is the diameter in centimetres. Determine the domain and range of the function if the tree has a diameter between 20 cm and 35 cm. Domain: 20 < d <35; Range: 34 < A<65 Domain: 20s d s 35; Range: 34
