domain of f(x)=(2x-2)/(9x+36)

domain

f (x) = \frac{2 x - 2}{9 x + 36}

x < - 4 or x > - 4

Interval Notation

(- \infty, - 4) \cup (- 4, \infty)

Solution steps

Find undefined (singularity) points:

x = - 4

The function domain

x < - 4 or x > - 4

f (x) = 5 + (ln (x^{2} - 9))^{2}

f (x) = x^{2} - 7 x + 12

f (x) = \frac{x + 4}{3 x ^{2} + 5 x + 2}

f (x) = 3 e^{x}

y = - x^{4} + 2 x^{2}

What is the domain of f(x)=(2x-2)/(9x+36) ?
The domain of f(x)=(2x-2)/(9x+36) is x<-4\lor x>-4
