domain of (2x^2+x-1)/(3x^2-11x-4)

domain

\frac{2 x ^{2} + x - 1}{3 x ^{2} - 11 x - 4}

x < - \frac{1}{3} or - \frac{1}{3} < x < 4 or x > 4

Interval Notation

(- \infty, - \frac{1}{3}) \cup (- \frac{1}{3}, 4) \cup (4, \infty)

Solution steps

Find undefined (singularity) points:

x = 4, x = - \frac{1}{3}

The function domain

x < - \frac{1}{3} or - \frac{1}{3} < x < 4 or x > 4

(0, 5), (6, 0)

(- 8, - 1), (- 1, - 2)

f (x) = \frac{x - 7}{x + 5}

m = 0, (6, - 7)

f (x) = \frac{x + 3}{x ( x + 9 )}
