The IVT is often used to verify that a function has a zero. For the following graph what would be the proper way to state the IVT theorem to show that there is a zero in the range? 0 x) is continuous on [-5, 5] and let it be zero. Then there exists a number c such that, f( c } = 0. 0 x) is continuous on [-5, -2] and let it be zero. Then there exists a number c such that. f( c ) = 0. 0 f(x) is continuous on [4, 5] and let it be zero. Then there exists a number c such that, f( c } = 0. 0 f(x) is continuous on [2, 5] and let it be zero. Then there exists a number c such that, f( c } = 0
