A function 'f' from a set X to Y is called onto if very y in Y , EE x in X such that f(x) =y . Unless the contrary is specified a real function is onto if it takes all real values ,Othervise ,it is called o into function , Thus , if X and Y are finite sets , then 'f' can not be onto if Y contains more elements then 'x' Now answer the following The polynomial function f(x) = a_0 x^(n) +a_1 x^(n-1) +a_2x^(n-2) +.......+a_n where a_0 ne 0 is onto for
