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

Solution

domain

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

Solution

x < - 1 or x > - 1

+1

Solution steps

Find undefined (singularity) points:

x = - 1

The function domain

x < - 1 or x > - 1

Popular Examples

range of f(x)= 3/x range

f (x) = \frac{3}{x}

inflection f(x)= 6/((x-1)^3)inflection points

f (x) = \frac{6}{( x - 1 ) ^{3}}

range of 1+x-x^2-x^3 range

1 + x - x^{2} - x^{3}

inverse of f(x)=((x-3))/(x+2)inverse

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

domain of f(x)=x^2-10x+25 domain

f (x) = x^{2} - 10 x + 25
