how do i find the exact value of point of infliction?

Question

anonymous · Answer

Utilizing the 2nd derivative, if you set the 2nd derivative = 0 and solve for x, then plug that x into f(x) , you should get the (x,y) coordinates of the point of inflection.  Correct me if I'm wrong, please!

anonymous · Answer

Inflection.

Same way as you find any other turning point (derivative = 0)

Except in this case the type of turn is different.

inflection point?

myininaya · Answer

make sure the concavity changes there

myininaya · Answer

by using test numbers around the possible inflection numbers

anonymous · Answer

2nd derivative is for testing.

The sign either side of  of the derivative will be the same for a point of inflection.

what happens if i get a critical point for the first derivative and when i plug it into the orginal function and the first derivative i get 0's does that mean anything?

anonymous · Answer

It means your point of inflection is at the origin.
