domain of f(x)= 1/(x^2-4x-5)

Solution

domain

f (x) = \frac{1}{x ^{2} - 4 x - 5}

Solution

x < - 1 or - 1 < x < 5 or x > 5

+1

Solution steps

Find undefined (singularity) points:

x = 5, x = - 1

The function domain

x < - 1 or - 1 < x < 5 or x > 5

Popular Examples

domain of f(x)=(8+x)/(1-8x)domain

f (x) = \frac{8 + x}{1 - 8 x}

inverse of f(x)=9-3x inverse

f (x) = 9 - 3 x

domain of sqrt(((x+4)(x+5))/(x-7))domain

\frac{( x + 4 ) ( x + 5 )}{x - 7}

range of y= 1/(x+2)range

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

inverse of 4x^3-5 inverse

4 x^{3} - 5
