domain of (x^2+x-30)/(x^2-4x-5)

domain

\frac{x ^{2} + x - 30}{x ^{2} - 4 x - 5}

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

Interval Notation

(- \infty, - 1) \cup (- 1, 5) \cup (5, \infty)

Solution steps

Find undefined (singularity) points:

x = 5, x = - 1

The function domain

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

f (x) = x^{2} - 12 x

f (x) = \frac{x + 7}{x ^{2} + 14 x + 49}

f (x) = (ln (x))^{l n (x)}

\frac{x ^{3}}{( 4 - x ) ^{2}}

4 x^{2} - 9
