What kind of relation can be obtained between the response of first order derivative and second order derivative of an image having a transition into gray-level step from zero?

What kind of relation can be obtained between the response of first order derivative and second order derivative of an image having a transition into gray-level step from zero? Correct Answer Both first and second order derivative has the same response

This is because a first order derivative has stronger response to a gray-level step than a second order, but, the response becomes same if transition into gray-level step is from zero.
