Hey, could someone help me with the following task about highs and lows?
Hey, I was asked to determine the peak and trough points of a certain function using the sign change criterion. I did just that.
Could someone help me with the second part of the task?:
How do I describe the course at the point X=0 (of f) without seeing the graph?
Thank you.
This is the monotony behavior. Easily f'(0) = ….
Positive result -> Increases
negative –> falls
It can then be written as an answer that the point (0/0) is a saddle point. You wouldn’t have to write more?
