domain of (2x)/(x^2+3x)

domain

\frac{2 x}{x ^{2} + 3 x}

x < - 3 or - 3 < x < 0 or x > 0

Interval Notation

(- \infty, - 3) \cup (- 3, 0) \cup (0, \infty)

Solution steps

Find undefined (singularity) points:

x = 0, x = - 3

The function domain

x < - 3 or - 3 < x < 0 or x > 0

y^{3} = x

f (x) = \frac{x + 1}{x ^{2} + x - 2}

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

f (x) = 3 x^{4} - 4 x^{3} - 12 x^{2}

\frac{\frac{x}{x - 1}}{\frac{1}{3 - x}}
