Toolkit 91Intermediate Value Theorem (IVT)If f is continuous on [a,b] and f(a)f(b)<0, then ∃ c∈(a,b) such that f(c)=0.\text{If }f\text{ is continuous on }[a,b]\text{ and }f(a)f(b)<0,\text{ then }\exists\,c\in(a,b)\text{ such that }f(c)=0.If f is continuous on [a,b] and f(a)f(b)<0, then ∃c∈(a,b) such that f(c)=0.
