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

domain

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

x < - 3 or - 3 < x < 2 or x > 2

Interval Notation

(- \infty, - 3) \cup (- 3, 2) \cup (2, \infty)

Solution steps

Find undefined (singularity) points:

x = - 3, x = 2

The function domain

x < - 3 or - 3 < x < 2 or x > 2

y = 9 - x

4 - 6 x

f (x) = x^{2} + 4 x + 4

f (x) = 2 e^{2 x}

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