Q. Find the second derivative of the function.f(x)=−x44−11x = ______
Find First Derivative: Find the first derivative of f(x).f′(x)=dxd(−x44−11)Using the power rule, dxd(xn)=n⋅x(n−1), and the derivative of a constant is 0.f′(x)=dxd(−4⋅x−4)−dxd(11)f′(x)=−4⋅(−4)⋅x−5−0f′(x)=16x−5
Find Second Derivative: Find the second derivative of f(x).f′′(x)=dxd(16x−5)Using the power rule again,f′′(x)=16∗(−5)∗x−6f′′(x)=−80x−6
