Given that x is a number there is not negative kelvin conjectured that x(to the 2nd power) > x+1 which value is a counterexample to kelvins conjecture? -1/2 -2 0 5

The way this is written, you cannot use -1/2 or -2. Is that correct? Both of them are minus. So the only things you have going for you is 0 and 5

x^2 > x + 1  when x = 5

5^2 > 5 + 1 and his conjecture is true.

25 > 6

What about 0?

0^2 = 0   so

0 > 0 + 1 and the conjecture is false.

answer: r there any options?
