Applying of the Bisection Method Manually By applying Intermediate Value Theorem several times in a nested interval, one can find an approximate answer of the zero of a function. I.
a) The function is continuous on the interval [a, b].
b) The function changes sign on the interval [a, b].
c) The function has a root in the interval [a, b].
d) The function's derivative is positive on the interval [a, b].
