Calculate f(2) and f(3).


If these two values have different signs, then the intermediate value theorem is applicable, 
and you may then conclude that the function f(x) has at least one zero in the interval (2,3).


Happy calculations, and I wish you to get fun by applying this remarkable intermediate value theorem.
