domain of (2x^2-2x-4)/(x^2+x-12)

domain

\frac{2 x ^{2} - 2 x - 4}{x ^{2} + x - 12}

x < - 4 or - 4 < x < 3 or x > 3

Interval Notation

(- \infty, - 4) \cup (- 4, 3) \cup (3, \infty)

Solution steps

Find undefined (singularity) points:

x = 3, x = - 4

The function domain

x < - 4 or - 4 < x < 3 or x > 3

y = 2 + 3 sin (2 x + \frac{π}{4})

\frac{17 x - 6}{6 x + 4}

f (x) = \frac{4 x}{x ^{2} - 6 x - 7}

f (x) = - 4 - 2 x + 1 - 2

\frac{3 x ^{2} - 9}{x - 1}
