Let's design the function. What should this function take as its parameters,
and what should it return? What value should the function compute?

We might also have chosen for bisection to take a tolerance as a third
parameter. That is, we might want to be able to specify, as part of each call
to bisection, how close f(root) should be to zero. For now, to
keep things simpler, let's build the tolerance directly into the function.
Notice also that we are not passing the function f as a parameter, as we
did in the Maple implementation. Instead, we are implementing f
elsewhere in the program so that it will be directly visible to
bisection.
So far, what does our function look like?
