domain of (x^2-1)/(4-x^2)

domain

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

- 4 2 x - 8

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

f (x) = \frac{1 - x ^{2} + x}{∣ x - 2 ∣ + 2}

f (x) = 5 x - 4

f (x) = lo g_{10} (6 x^{2} - 13 x - 28)
