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

Solution

domain

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

domain of f(x)=(x-4)/(x^2+8x+16)domain

f (x) = \frac{x - 4}{x ^{2} + 8 x + 16}

domain of f(x)=(3+|x|)/(2x^2+5x-3)domain

f (x) = \frac{3 + ∣ x ∣}{2 x ^{2} + 5 x - 3}

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

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

asymptotes of (4x^2)/(x^2+4)asymptotes

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

perpendicular y= 3/4 x,(20,15)perpendicular

y = \frac{3}{4} x, (20, 15)
