domain of (8x+9)/(7x-8)

domain

\frac{8 x + 9}{7 x - 8}

x < \frac{8}{7} or x > \frac{8}{7}

Interval Notation

(- \infty, \frac{8}{7}) \cup (\frac{8}{7}, \infty)

Solution steps

Find undefined (singularity) points:

x = \frac{8}{7}

The function domain

x < \frac{8}{7} or x > \frac{8}{7}

f (x) = \frac{x + 5}{( x - 7 ) ( x - 2 )}

f (x) = 5 + 4 x - x^{2}

y = 5 x - 3

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

f (x) = \frac{x ^{2} - 16}{x ^{2} - x - 6}

What is the domain of (8x+9)/(7x-8) ?
The domain of (8x+9)/(7x-8) is x< 8/7 \lor x> 8/7
