Step-by-step explanation:
the image is unique. → If A and B are finite sets such that n(A) = p; n(B) = q then the total number of functions that exist from A to B is q”. In this chapter we always consider f to be a real valued function. Describing domain of a function - 1 (i) Let f(2) If x = -1 then f(-1) is not defined. Hencef is defined for x +1 all real numbers except at x = -1. So, domain of f is R-{-1}. 1 (ii) Let f(x) = ; If r = 2,3 then f (2) and f (3) are not defined.
