Confusing Question: With the given information sketch the graph Confusing Question: With the given information sketch the graph @Mathematics
Thanks
Assume that the function is defined and continous for all points on the domain
yeah i am not sure what this is saying. is it saying that the first derivative is positive then negative?
ok i will explain
It is firstly saying that at x1 and x2 the first derivative is equal to zero
ok i think i get it. it looks like at x2 the first derivative goes from being negative to positive. that means your function has a local minimum there. function was decreasing, then increasing
The function is increasing until it reaches x1 at x1 it begins to decrease until x2 and at x2 it bebegins increasing again
but notice that at x1 it is undefined
yes, and the derivative changes sign there, so it could look like this|dw:1321588281375:dw|
i think that may be wrong
notice in the picture i drew the first derivative goes from being positive to negative but is undefined the corner. also the second derivative is positive always except at the corner, where it does not exist
because look at the second derivative it is concave up b4 and after x1
yes it could be wrong, but it fits with the information you are given
the picture i drew is concave up on both sides
and at x2 the first derivative is equal to zero
oh sorry i was just drawing around x1
but I think i can just add a litlle curve
and it will be fine
to show how the first derivative could be positive and then negative, but undefined at the point. i will draw more
Thanks satellit you are the best!!! ;D
