critical f(x)=x^2+x-2

critical points

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

x = - \frac{1}{2}

Solution steps

x^{2} + x - 2

Find where

f^{'} (x)

is equal to zero or undefined

x = - \frac{1}{2}

Identify critical points not in

f (x)

domain

Domain of

x^{2} + x - 2 : - \infty < x < \infty

All critical points are in domain

x = - \frac{1}{2}

(\frac{1}{2}, \frac{1}{3}), (\frac{3}{2}, \frac{- 5}{3})

f (x) = 2.2 + 2.2 x - 0.6 x^{2}

x^{3} - 9 x^{2} + 15 x - 8

f (x) = 3 x - 12

f (x) = e^{x}
