critical f(x)=(2x+3)/(x+2)

critical points

f (x) = \frac{2 x + 3}{x + 2}

None

Solution steps

\frac{2 x + 3}{x + 2}

Find where

f^{'} (x)

is equal to zero or undefined

x = - 2

Identify critical points not in

f (x)

domain

Domain of

\frac{2 x + 3}{x + 2} : x < - 2 or x > - 2

\frac{2 x + 3}{x + 2}

is not defined at

x = - 2

, therefore:

None

x x - x^{2}

(x^{2} + y^{2}) e^{y^{2} - x^{2}}

\frac{4 x}{x ^{2} - 4}

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

- 294 \cdot x + 2 \cdot x^{3} + 6 \cdot x \cdot y^{2} - 3 \cdot y^{3}
