Answer 1

B .
`f(x+h)=(x+h)/(1+x+h)`

Explanation:

Given function is:

`f(x)=(x)/(1+x)`

Sall h is used to denote minor change in function. The value of the new function f(x+h) will be calculated by putting x+h in place of x in the function.

So putting x+h in place of x

`f(x+h)= (x+h)/(1+(x+h))\\=(x+h)/(1+x+h)`

So, option B is the correct answer ..
