What would a counter-example be in math?


a.an example that proves the conjecture wrong
b.an example to show the formula is wrong
c.a very nice granite kitchen-top surface
d.an example to show the conjecture is true

Since this is not my area of expertise, I searched Google under the key words "math counterexample" to get this:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

The correct answer is a. A counter-example in math is an example that disproves a conjecture or statement. It is an instance where the given conditions of a statement are met, but the conclusion of the statement is false. Counter-examples are used to show that a statement or conjecture is not always true, even if it appears to be true for several instances. To find a counter-example, you would try to find a specific case or scenario that contradicts the given statement or conjecture.
