Suppose that the function j' has an inflrction point at x=2. What, if anything does this imply about
(a) j"?
(b) j?
I do not understand derivatives. I know you have to base your answer off the information given but I don't understand how to do that. Is it like since x=2 that means j(x) > 0 so would j(2)=3 and j"(2)=-3. Im really not sure can someone please explain derivatives to me. Thank you
The point of inflection is x=2 and you find the inflection point when the concavity switches direction so it would be switching to concave down so would j''(2)= -3. I have yet to full grasp the concept of derivatives. Do you just make guess in order to get answers?
