domain of f(x)=(5x+14)/(6x^2+x-2)

domain

x < - \frac{2}{3} or - \frac{2}{3} < x < \frac{1}{2} or x > \frac{1}{2}

Interval Notation

(- \infty, - \frac{2}{3}) \cup (- \frac{2}{3}, \frac{1}{2}) \cup (\frac{1}{2}, \infty)

Solution steps

Find undefined (singularity) points:

x = \frac{1}{2}, x = - \frac{2}{3}

The function domain

x < - \frac{2}{3} or - \frac{2}{3} < x < \frac{1}{2} or x > \frac{1}{2}

What is the domain of f(x)=(5x+14)/(6x^2+x-2) ?
The domain of f(x)=(5x+14)/(6x^2+x-2) is x<-2/3 \lor-2/3 <x< 1/2 \lor x> 1/2
