Solution steps

Find undefined (singularity) points:

x = - 1

The function domain

x < - 1 or x > - 1

Popular Examples

intercepts of f(x)=x^2-4x+7 intercepts

f (x) = x^{2} - 4 x + 7

domain of f(x)= 1/(x^2-3x+2)domain

f (x) = \frac{1}{x ^{2} - 3 x + 2}

inverse of f(x)=ln(3x+1)inverse

f (x) = ln (3 x + 1)

domain of f(x)=(sqrt(5+x))/(5-x)domain

f (x) = \frac{5 + x}{5 - x}

domain of x+6 domain

x + 6
