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
Other than the obvious, the difference between the male and female Golden Retriever is predominately size. Females are normally between 50-60 lbs and males are 65-80 lbs. Of course this can vary because of genetics.
