domain of f(x)=(2x-7)/(9x+2)

domain

f (x) = \frac{2 x - 7}{9 x + 2}

x < - \frac{2}{9} or x > - \frac{2}{9}

Interval Notation

(- \infty, - \frac{2}{9}) \cup (- \frac{2}{9}, \infty)

Solution steps

Find undefined (singularity) points:

x = - \frac{2}{9}

The function domain

x < - \frac{2}{9} or x > - \frac{2}{9}

\frac{8 x ^{2} + 12 x}{9 x ^{2} - 12 x + 4}

\frac{- x ^{2} + 7 x - 10}{x - 3}

f (x) = 1 - \frac{x ^{2}}{16}

f (x) = \frac{1 - 3 x}{x ^{3} - 4 x ^{2} - 5 x}

\frac{\frac{2}{x}}{\frac{4}{x + 4}}

What is the domain of f(x)=(2x-7)/(9x+2) ?
The domain of f(x)=(2x-7)/(9x+2) is x<-2/9 \lor x>-2/9
