Find the derivative of the function f(x)=x3−4x2+6x−2, and then simplify the expression |f′(2)|.
Finally, we simplify the absolute value expression |f′(2)|. Since f′(2)=2 and 2 is positive, we have |f′(2)|=|2|=2.
Step 1 :First, we find the derivative of the function f(x)=x3−4x2+6x−2. Using the power rule for derivatives, we have f′(x)=3x2−8x+6.
Step 2 :Then, we substitute x=2 into f′(x), giving us f′(2)=3(2)2−8(2)+6=12−16+6=2.
Step 3 :Finally, we simplify the absolute value expression |f′(2)|. Since f′(2)=2 and 2 is positive, we have |f′(2)|=|2|=2.
