Newton's method is being used to approximate the non-zero -intercept of the function with the equation  .  An initial estimate of  is used.

Which one of the following gives the first estimate that would correctly approximate the intercept to three decimal places?

5. The intercept cannot be correctly approximated using Newton's method.

The following algorithm applies Newton's method using a For loop with 3 iterations.

The Return value of the function    is closest to
