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

Solution

domain

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

Solution

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

+1

Solution steps

Find undefined (singularity) points:

x = 1, x = - 1

The function domain

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

Popular Examples

y = - 6

inverse of f(x)=(5x)/6+9 inverse

f (x) = \frac{5 x}{6} + 9

intercepts of f(x)=3x^2-x-2 intercepts

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

intercepts of (2x^2-5x+5)/(x-2)intercepts

\frac{2 x ^{2} - 5 x + 5}{x - 2}
