domain of f(x)=(x+1)/(x^2-9x+8)

Solution

domain

f (x) = \frac{x + 1}{x ^{2} - 9 x + 8}

Solution

x < 1 or 1 < x < 8 or x > 8

+1

Solution steps

Find undefined (singularity) points:

x = 8, x = 1

The function domain

x < 1 or 1 < x < 8 or x > 8

Popular Examples

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

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

domain of (x+5)/3 domain

\frac{x + 5}{3}

domain of f(x)=cos(x-7)+4 domain

f (x) = cos (x - 7) + 4

domain of f(x,y)=ln(x-6)domain

f (x, y) = ln (x - 6)

domain of e^{7x}domain

e^{7 x}
