domain of (3x^2-12)/(4-x^2)

domain

\frac{3 x ^{2} - 12}{4 - x ^{2}}

x < - 2 or - 2 < x < 2 or x > 2

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 2, x = - 2

The function domain

x < - 2 or - 2 < x < 2 or x > 2

f (x) = x^{2} - x

2 x^{2} + 4

f (x) = - 3

lo g_{\frac{1}{5}} (x)

\frac{8 x - 1}{2 x + 5}
