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
Never the types to fixate on a single person, Goldens get along with the whole family and are especially patient and outgoing with children. However, a high-energy Golden Retriever (especially a young one) can accidentally bump into or knock over a child during play. Like most dogs their size, Golden Retrievers normally live between 10-12 years.
