domain of y= 1/(3x+6)

domain

y = \frac{1}{3 x + 6}

x < - 2 or x > - 2

Interval Notation

(- \infty, - 2) \cup (- 2, \infty)

Solution steps

Find undefined (singularity) points:

x = - 2

The function domain

x < - 2 or x > - 2

- \frac{1}{2} x^{2}

f (x) = x^{2} + 8 x + 15

\frac{297 \cdot x}{512}

f (x) = ln (0.5 - x)

\frac{5}{x ^{2} - 4}
