An explicit definition of a function f gives an algorithmic procedure, usually given by an algebraic formula, that produces the output (dependent variable) of f for a given input (independent variable); for example, f(x) = x2.
Golden Retrievers are 1 foot 9 inches tall to 2 feet tall. You can say they are of medium size. They weigh 55 to 75 pounds and live for 10 to 12 years. I hope this will help you. Regards, Perrie Jinnie Pet Grooming Tips
With regards to how much a golden retriever should weigh, we have consulted the FCI Standards Commission. Here, reference is given to height, but not to weight. The height at the withers for males should be between 56 and 61 cm (22-24 in), and between 51 and 56 cm (20-22 in) in females. With regards to weight - though it does not give a specific figure - it states clearly that this breed should have a balanced appearance. It should be strong and muscular, and should remain very active. If you have a golden retriever, you should make sure it stays at a healthy weight. 3. Although the FCI does not indicate a specific weigh, we can establish if a male adult golden retriever is healthy and fit if it weighs around 35 kilos. Females, on the other hand, should weigh around 30 kilos.
