    Does anyone have an equation that works for both the Newton Raphson method and the Rearranging method?! My deadline was yesterday and all the ones try don't work for one or the other

    You can use the quadratic equation 2ax^2+bx+c

    For NR, let f(x)=2ax^2+bx+c, with suitable values for a,b,c such that there is a solution.

    For the rearrangement method, rearrange 2ax^2+bx+c=0 to give x=\frac{ax^2-c}{2ax+b}

    Now ensure that the values for a,b,c that you chose for the NR eqn give g(x)=\frac{ax^2-c}{2ac+b} such that |g(x)|<1
