If f:R rarr R and f(x)=g(x)+h(x) where g(x) is a polynominal and h(x) is a continuous and differentiable bounded function on both sides, then f(x) is one-one, we need to differentiate f(x). If f'(x) changes sign in domain of f, then f, if many-one else one-one. If f: R rarr R and f(x)=a_(1)x+a_(3)x^(3)+a_(5)x^(5)+...+a_(2n+1)-cot^(-1)x " where " 0 lt a_(1) lt a_(3) lt ... lt a_(2n+1), then the function f(x) is |
