Given that x is a nonnegative number, a student conjectured that x+3 Which value of x is a counterexample to the student's conjecture?

X= -1/3

X= -3

X= 2

X= 3

Step-by-step explanation:

Given

Conjecture: --- (Missing)

Required

Which value of x prove the conjecture otherwise

To do this , we simply substitute the values of x in the options

This is negative;

So, there is no need to check

This is also negative;

So, there is no need to check

This value of x is false because 5 is not less than 4
