domain of ((6+x)(3+x))/(-3-4x)

domain

\frac{( 6 + x ) ( 3 + x )}{- 3 - 4 x}

x < - \frac{3}{4} or x > - \frac{3}{4}

Interval Notation

(- \infty, - \frac{3}{4}) \cup (- \frac{3}{4}, \infty)

Solution steps

Find undefined (singularity) points:

x = - \frac{3}{4}

The function domain

x < - \frac{3}{4} or x > - \frac{3}{4}

- 3.3

f (x) = \frac{6}{25 - x ^{2}}

6 x^{2} - 15 x

f (x) = 4 x^{2} - 8 x - 3

f (x) = 4 x^{2} - 8 x + 3

What is the domain of ((6+x)(3+x))/(-3-4x) ?
The domain of ((6+x)(3+x))/(-3-4x) is x<-3/4 \lor x>-3/4
