- Homework Statement
- This is a question from my own paper;

This is the second part of the question that i am marking...the first part was on finding the stationary points.

Determine the co ordinates of the maximum point of the graph amended to ;Determine which stationary point is a maximum. Giving reasons for your answer.

##y=x^4-4x^2##

- Relevant Equations
- differentiation

I am marking this now...just need your insight...the second part has [2] marks. I am giving [1] mark for the correct method...i expect use of second derivative test or otherwise for Method Mark...then the correct answer ##(0,0)## would realize the Answer mark.

The student has not shown any method but has indicated only the answer i.e ##(0,0)## which is correct, how to handle this? based on my previous experience of marking A level papers for an [International Examining body] ...i was advised that one cannot get Answer mark correct if the given Method is not correct or is not shown. Cheers.
