WebNote that this answer assumes the function is increasing, and will give the wrong answer if the function is decreasing. (Also it will give the wrong answer if there is no root in the specified interval.) WebFor the function, simply pass the function name as an argument. I've changed your function's name to root11 and made it the first argument to the bisection.. For the count ... you should have been able to look this up on line. Just count iterations as you would before you learned the for statement. Return this with the final answer.
