domain of (x^2-8x+15)/(x+3)

domain

\frac{x ^{2} - 8 x + 15}{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

- 4 x + 10

f (x) = 5 x^{6}

\frac{ln ( 2 x )}{x}

f (x) = \frac{1}{9 + x}

f (x) = 5 x + 25
