Best ResponseYou've already chosen the best response.0usually the intermediate value theorem is used to show that a zero exist but we can't use it to show that it doesn't exist. In this case I just suspicious because I couldn't show that it has a zero using the intermediate value theorem. So I graph it and see that there is no zero between 2 and 1.
