domain of (2x+2)/(x^2-7x-8)

domain

\frac{2 x + 2}{x ^{2} - 7 x - 8}

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

Solution steps

Find undefined (singularity) points:

x = 8, x = - 1

The function domain

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

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

\frac{6}{11} (x^{2} - 9)^{\frac{2}{3}}

- \frac{1}{3} cos (3 x)

(x - 2)^{3} (x - 1)

f (x) = \frac{7 x - 4}{8}

What is the domain of (2x+2)/(x^2-7x-8) ?
The domain of (2x+2)/(x^2-7x-8) is x<-1\lor-1<x<8\lor x>8
