domain of f(x)=(x^2+5x-6)/(x^2-5x-6)

domain

f (x) = \frac{x ^{2} + 5 x - 6}{x ^{2} - 5 x - 6}

x < - 1 or - 1 < x < 6 or x > 6

Interval Notation

(- \infty, - 1) \cup (- 1, 6) \cup (6, \infty)

Solution steps

Find undefined (singularity) points:

x = 6, x = - 1

The function domain

x < - 1 or - 1 < x < 6 or x > 6

\frac{- 2 - 5 x}{3 x - 1}

f (x) = - \frac{1}{x ^{2} + 7}

f (x) = \frac{t}{t + 1}

6 (x + 1)^{2} - 5 (x + 1) - 1

f (x) = 15 x^{4} - 15 x^{2}
