domain of (5x-2)/(7x+3)

domain

\frac{5 x - 2}{7 x + 3}

x < - \frac{3}{7} or x > - \frac{3}{7}

Interval Notation

(- \infty, - \frac{3}{7}) \cup (- \frac{3}{7}, \infty)

Solution steps

Find undefined (singularity) points:

x = - \frac{3}{7}

The function domain

x < - \frac{3}{7} or x > - \frac{3}{7}

4 cos (x) sin (x) - 4 sin (x)

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

f (x) = - 4 x - 3

x + 1

f (x) = 10 - 2 x^{3}

What is the domain of (5x-2)/(7x+3) ?
