Showing a Zero of f(x) Using Bolzano's Theorem

[shiloh]

Use the intermediate value theorem to show that f(x) has a zero in the given interval. Please show all of your work.
f(x)=-3x³+6x²-4x+12;[2.2,2.3]

have to use the Bolzano's Theorem(special case of the intermediate value theorem
can someone please help me out with this problem?
