Explanation:
Given function is:
![f(x)=(x)/(1+x)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/yy36mpjvdtsc0vnsg4hpbysx0rot70q7bt.png)
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)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/ii0q32mu9yh03z3s8q0ywyi5sc98wgl9b7.png)
So, option B is the correct answer ..
