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

domain

\frac{- 4 + 2 x ^{2}}{x ^{2} - 1}

x < - 1 or - 1 < x < 1 or x > 1

Interval Notation

(- \infty, - 1) \cup (- 1, 1) \cup (1, \infty)

Solution steps

Find undefined (singularity) points:

x = 1, x = - 1

The function domain

x < - 1 or - 1 < x < 1 or x > 1

f (x) = 5 x + 4 y = 20

f (x) = x^{(2)} + 2 x - 3

f (x) = 5 x^{4} - 30 x^{2}

f (x) = x^{4} + 3 x^{3}

f (x) = ln (x - 6)
