domain of (x^3+7x^2+14x+9)/(x^2+2x-3)

domain

\frac{x ^{3} + 7 x ^{2} + 14 x + 9}{x ^{2} + 2 x - 3}

x < - 3 or - 3 < x < 1 or x > 1

Interval Notation

(- \infty, - 3) \cup (- 3, 1) \cup (1, \infty)

Solution steps

Find undefined (singularity) points:

x = 1, x = - 3

The function domain

x < - 3 or - 3 < x < 1 or x > 1

\frac{6 x}{x ^{2} + 16}

f (x) = \frac{x - 8}{x ^{2} - 3 x + 2}

f (x) = x + 5

y - 3 = 5 (x - 6)

y = \frac{3}{t}
