Solution

The correct option is B proper subset
For f(x) to be an into function, the codomain must have an element that is not mapped to any of the elements in the domain of f.
Hence, the range of f(x) should be a proper subset of its codomain.

Let

f : A \to B

be a function defined by

y = f (x)

where f is a bijective function, means f is injective (one-one) as well as surjective (onto), then there exist a unique mapping

g : B \to A

such that

f (x) = y

if and only if

g (y) = x \forall x ϵ A, y ϵ B

Then function g is said to be inverse of f and vice versa so we write

g = f^{- 1} : B \to A [{f (x), x} : {x, f (x)} ϵ f^{- 1}]

when branch of an inverse function is not given (define) then we consider its principal value branch.

Q. Assertion :

f

is even,

g

is odd then

\frac{f}{g} (g \neq 0)

is an odd function. Reason: If

f (- x) = - f (x)

for every

x

of its domain then

f (x)

is called odd function and if

f (- x) = f (x)

for every

x

of its domain, then

f (x)

is called even function.
