Hi. Im stuck on this problem:

Consider the function:

$\displaystyle f(x) = x+2$ if $\displaystyle x \le 2$

$\displaystyle f(x) = 8-x$$\displaystyle otherwise

$

Discuss the applicability ofNewton-Raphsonandgolden section search: will they successfully approximate the minimum in $\displaystyle [-3,5]$ to within a pre-specified tolerance?

I am thinking no? because there are no such minimium for the graph, since it is totally unbounded. Am I on the right track? How can I explain this in terms of those methods mentioned in the question?

Thanks.
