Gud day! :)
I just want to know what is the correct answer in this problem:
Equation:
y = 1/3 x^3 - 1/2 x^2 - 2x
the point of inflection that I got is (1/2 , -3/4) but according to the book its (1/2, -13/12). How do they get that?
thanks! :)

Just evaluate the original equation for x = 1/2.
I think thr is some error in your ans.. for x=1/2, the only value for y is -13/12..
They found the second derivative, set to 0 and solved for x.Quote:

Plug back into original equation:
