A function is a relation between two sets defined in such a way that for each element in the first set, the value that corresponds to it in the second set is unique. Let f be a function defined from the set A into set B. Then for each x Ïµ A, the symbol f (x) denotes the unique value in the set B that corresponds to x. It is called the image of x under f. Therefore, a relation f from A into B is a function, if and only if for, each xÏµ A and y Ïµ A; if x = y then f (x) = f (y). The set A is called the domain of the function f, and it is the set in which the function is defined. For example, consider the relation f from R into R defined by f (x) = x + 2 for each xÏµ A. This is a function whose domain is R, as for each real number x and y, x = y implies f (x) = x + 2 = y + 2 = f (y).
Hairspray is a 1988 American romantic musical comedy film written and directed by John Waters, and starring Ricki Lake, Divine, Debbie Harry, Sonny Bono, Jerry Stiller, Leslie Ann Powers, Colleen Fitzpatrick, and Michael St. Gerard.
AllMusic Review by William Ruhlmann. Hairspray began life in 1988 as the first John Waters film to earn a PG rating, despite such subversive elements as the casting of cross-dressing Waters favorite Divine as Edna, the mother of the main character, tubby teenager Tracy Turnblad.llMusic Review by William Ruhlmann.
