The points of inflection are
To calculate points of inflection you have to find zeros of the 2nd derivative and check if it changes sign at those points.
Looking for the points where
Checking if the derivative changes sign
graph{-12x^2+2 [-4.506, 4.505, -2.252, 2.254]}
From the graph we see that the derivative changes sign in both points
