Question

Find, if any, the local maximum, local minimum, and inflection points for y’ = 2x^2 – x – 3.

Answer 1

y' is correct right?

(2x-3)(x+1)

x = 3/2 and x=-1 are bending points

y'' = 4x-1 at x=-1 we have a (-)value its a MAX

at x = 3/2 we will have a (+) value..its a MIN

at x = 1/4 we should have an inflection
