domain of (10x)/(x+4)

domain

\frac{10 x}{x + 4}

x < - 4 or x > - 4

Interval Notation

(- \infty, - 4) \cup (- 4, \infty)

Solution steps

Find undefined (singularity) points:

x = - 4

The function domain

x < - 4 or x > - 4

y = x^{2} - 4 x

f (x) = \frac{1}{4} x - \frac{1}{8}

f (x) = - x + 4 - x + 4

lo g_{10} (8) (12 - 4 x)

f (x) = \frac{6 x}{2 x + 1}
