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
The AKC's Golden Retriever Standard states that males should weigh 65-75 pounds and stand 23-24 inches tall when measured at the top of the withers (shoulders). Females should weigh 55-65 pounds and stand 21.5-22.5 inches tall. Many breeders do not stick to these guidelines when breeding Goldens, unless they are strictly showing dogs and trying to achieve this as part of their breeding program. Many prefer a larger Golden and therefore continue to breed dogs that are larger than the standard recommends.
