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

Solution

domain

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

Solution

x < 0 or x > 0

+1

Solution steps

Find undefined (singularity) points:

x = 0

The function domain

x < 0 or x > 0

Popular Examples

inverse of f(x)=3+sqrt(8+x)inverse

f (x) = 3 + 8 + x

slope of m= 9/2 slope

m = \frac{9}{2}

extreme f(x)=-x^3+9x^2-54 extreme points

f (x) = - x^{3} + 9 x^{2} - 54

asymptotes of f(x)=((x^3-64))/((x^2-9x+20))asymptotes

f (x) = \frac{( x ^{3} - 64 )}{( x ^{2} - 9 x + 20 )}

line x+3y=6 line

x + 3 y = 6
