We know that when X one equals d, the tangent line intersects with the X axis far off to the left not particularly close. Therefore, we know that X two intersex the X axis further away to the right. Therefore, we know Newton's method would failed for this initial approximation there for a being C will work. However, we already established why d may not work given New Newton's method.
