I got one function f(x)=x+1 .I want to know if there exist any other functions satisfying the equation ,if not,how to prove it.
I assumed that f(x)>x+1 in one case and f(x)<x+1 in other case. In both cases i am not able contradict something but instead i am getting some conditions on x,y...etc.
Please help.

Did you solve the last geometry question given in our practice paper(1). i think the question is wrong since BDC is a straight line and 3x doesnt make sense.

Remember to wrap math in \( ... \) or \[ ... \] to ensure proper formatting.`2 \times 3`

`2^{34}`

`a_{i-1}`

`\frac{2}{3}`

`\sqrt{2}`

`\sum_{i=1}^3`

TopNewest@Harsh Shrivastava- Yes. For the question, how will one prove that there doesnt exist any function other than f(x)=x+1.
