domain of (2x-6)/(x+3)

domain

\frac{2 x - 6}{x + 3}

x < - 3 or x > - 3

Interval Notation

(- \infty, - 3) \cup (- 3, \infty)

Solution steps

Find undefined (singularity) points:

x = - 3

The function domain

x < - 3 or x > - 3

y = - x^{2} - 8

f (x) = \frac{x ^{2} - 5 x + 6}{x ^{2} - 4}

y = \frac{2 x - 4}{x ^{2} - 4}

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

y = lo g_{8} (x)

What is the domain of (2x-6)/(x+3) ?
The domain of (2x-6)/(x+3) is x<-3\lor x>-3
