x=0 is a counterexample to Kelvin's conjecture.
Explanation:-
Given that x is a number that is not negative, Kelvin conjectured that![x^2x+1](/tpl/images/0057/0745/7a951.png)
A counter example is an example that contradicts or opposes the conjecture.
Thus -12 and -2 cannot be the value of x for the counter example as they are negative
The positive numbers in options are 0 and 5,such that
Thus the value of x=0 contradicts the conjecture made by Kevin.
⇒x=0 is a counterexample to Kelvin's conjecture.
