domain of f(x)=(-5x-6)/(-15x-28)

domain

f (x) = \frac{- 5 x - 6}{- 15 x - 28}

x < - \frac{28}{15} or x > - \frac{28}{15}

Interval Notation

(- \infty, - \frac{28}{15}) \cup (- \frac{28}{15}, \infty)

Solution steps

Find undefined (singularity) points:

x = - \frac{28}{15}

The function domain

x < - \frac{28}{15} or x > - \frac{28}{15}

\frac{1}{x - 2}

\frac{x - 3}{x - 6}

- 3 cos (4 x)

x^{5} + 5 x^{4}

6 x - 18

What is the domain of f(x)=(-5x-6)/(-15x-28) ?
The domain of f(x)=(-5x-6)/(-15x-28) is x<-28/15 \lor x>-28/15
