Excel screen shots are acceptable but the algebra must be shown. Each illustration should match the iterates used. In fact, in your case I would say it's more sensible if you're doing the change of sign method to say it's This could include how well they worked, what the significance of failure possibilities etc.

This is not enough — only the graph has been drawn. It should be clear that Newton-Raphson always works! The mark for the error bounds can be given but not the root.

For a meaningful comparison of speed of convergence you should also start with the same initial value. In this example there is a root in the interval [1, 2]. Therefore, candidates should write equations. One of these values is called a root In the first and third domain one root is required. If this is not done then a penalty should be applied.

Excel screen shots are acceptable but the algebra must be shown. One of these values is called a root In the first and third domain one root is required. It should be clear that Newton-Raphson always works! Surely that covers all the possible values in my range? For a meaningful comparison of speed of convergence you should also start with the same initial value.
