MathematicsEasy175×since 2002Q2677Let x=2x=2x=2 be a local minima of the function f(x)=2x4−18x2+8x+12,x∈(−4,4)f(x)=2x^4-18x^2+8x+12,x\in(-4,4)f(x)=2x4−18x2+8x+12,x∈(−4,4). If M is local maximum value of the function fff in (−4,4)-4,4)−4,4), then M =A186−33218\sqrt6-\frac{33}{2}186−233B186−31218\sqrt6-\frac{31}{2}186−231C126−33212\sqrt6-\frac{33}{2}126−233D126−31212\sqrt6-\frac{31}{2}126−231Check answerSkip
