domain of (x^2-4)/(9x+4)

domain

\frac{x ^{2} - 4}{9 x + 4}

x < - \frac{4}{9} or x > - \frac{4}{9}

Interval Notation

(- \infty, - \frac{4}{9}) \cup (- \frac{4}{9}, \infty)

Solution steps

Find undefined (singularity) points:

x = - \frac{4}{9}

The function domain

x < - \frac{4}{9} or x > - \frac{4}{9}

\frac{2 x - 6}{x ^{2} + 2 x - 15}

f (x) = \frac{1}{x ^{2} - x - 12}

f (x) = (\frac{x + 3}{x - 1})

4 - x^{2} + \frac{x + 2}{11 - x}

f (x) = e^{s i n (\frac{π}{x})}

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