For each n = 1,2,3, define fn(x)x(1- t), for every e (-1,1]. let f : r2-r be defined by f(2, y)) = x2e 2 2y, for every (x, y) e r2. then the function fdefined by f(x): = lim fn(x) f(0,0)) + fm (0,0)) is: the value of f((0,0)) + noo exists for each x e [-1,1] and is equal to select one: select one: undefined f(x) 0 a = 1 -2 o 0 f(x)= 0 o a

The length of a rectangular board is 3 feet less than twice its width. a second rectangular board is such that each of its dimensions is the reciprocal of the corresponding dimensions of the first rectangular board. if the perimeter of the second board is one-fifth the perimeter of the first, what is the perimeter of the first rectangular board?
