Inflection points definition

An inflection point is a point on the graph at which the second derivative is equal to zero or undefined and changes sign.
If f ′′(x)>0 then f(x) concave upwards.
If f ′′(x)<0 then f(x) concave downwards.

f ′′(x)=36x²−4

Find intervals: Concave Upward:−∞ <x<−13 , Concave Downward:−13 <x<13 , Concave Upward:13 <x<∞

Plug x=−13 into 3x⁴−2x²: −527
