critical f(x)=|x^2-2x-3|

critical points

f (x) = x^{2} - 2 x - 3

x = - 1, x = 1, x = 3

Solution steps

x^{2} - 2 x - 3

Absolute value functions are piecewise functions

Find the function intervals:

x < - 1, x = - 1, - 1 < x < 3, x = 3, x > 3

Evaluate the function behavior for each interval

Find where

f^{'} (x)

is equal to zero or undefined

x = - 1, x = 1, x = 3

f (x) = 9 x^{6} (3 - x)^{5}

+ 3 cot (\frac{1}{2} x) - 2

f (x) = 2 x 100 - x^{2}

f (x) = 3 x^{4} - 4 x^{3} - 12 x^{2} + 1

f (x, y) = x^{2} + 2 x^{2} y + y^{3}
