domain of f(x)=(x^2-3x+2)/(x^2+7x+12)

domain

f (x) = \frac{x ^{2} - 3 x + 2}{x ^{2} + 7 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

f (x) = \frac{6}{x + 3}

f (x) = 3 ln ∣ 3 x - 5 ∣ + 2

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

y = \frac{x ^{2} - 1}{x ^{2} + 4}

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