domain of y=(x-1)/(x^2-9)

Solution

domain

y = \frac{x - 1}{x ^{2} - 9}

Solution

x < - 3 or - 3 < x < 3 or x > 3

+1

Solution steps

Find undefined (singularity) points:

x = 3, x = - 3

The function domain

x < - 3 or - 3 < x < 3 or x > 3

Popular Examples

ln (x + 6)

range of x+3 range

x + 3

range of (0.052x)/(0.9+0.048x)range

\frac{0.052 x}{0.9 + 0.048 x}

slope of 5x-2y=3 slope

5 x - 2 y = 3

asymptotes of f(x)=(x^2+x-6)/(x-4)asymptotes

f (x) = \frac{x ^{2} + x - 6}{x - 4}
