If f(x) is a one to one function, where f(x)=x^(2)-x+1 , then find the inverse of the f(x):

If f and g are one-one functions, then a. f+g is one one b. fg is one one c. fog is one one d. none of these

f:RrarrR given by f (x) = 2x is one-one function.

Statement-1 : If f(x) and g(x) are one-one functions then f(g(x)) and g(f(x)) is also a one-one function. and Statement-2 The composite function of two one-one function may or many not be one-one.

Statement-1 : If f(x) and g(x) are one-one functions then f(g(x)) and g(f(x)) is also a one-one function. and Statement-2 The composite function of two one-one function may or many not be one-one.

Let g(x)=x^(2)-4x-5 then g(x) is (A) is one-one on R (B) g is one - one on (-oo,2] (C) g is not one-one on (-oo,4] (D) g is one - one on (-oo,0)

Which of the following statements are incorrect? 1.If f(x) and g(x) are one-one then 2. f(x)+g(x) is also one-one If f(x) and g(x) are one-one then 3. f(x)dotg(x) is also one-one If f(x) is odd then it is necessarily one-one?
