Question

How do you find the x and y coordinates of the relative maximum value given the graph of the derivative?

Answer 1

From what I know the relative maximum and relative minimums in a graph will intersect the x- axis when graphing it's derivative

Answer 2

Alright - Thank you so much! Do you know whether it would go from + to - or - to +?

Answer 3

So basically if it hit the x- line

Answer 4

I forgot about that sorry

Answer 5

Lol, it's fine. Thank you.

Answer 6

So would the max be the point on the right that crosses the x axis?

Answer 7

Ok I found out. + from the left of the critical point and - from the right means it's a maximum

Answer 8

Ohh - okay! Thanks!

Answer 9

That's a maximum because it's positive from the left and negative from the right.

Answer 10

It's a minimum if it's - from the left and + from the right

If it's neither then it's not a maximum or minimum

Answer 11

Thank you. :)
