After differentiation, how do we know if its the max or mini point?

[@felixfire9513]

differintiate it again (its called double differintiation/ finding nature of turning point) and then substitute ur value of x in the equation. if final answer is positive, then its a minimum point but if negative then its max point.

[@bigchungus971]

if coefficient of x^2 is greater than 0 then its min point, if its less than 0 then its max point.
