domain of f(x)=(5x)/(7x-9)

domain

f (x) = \frac{5 x}{7 x - 9}

x < \frac{9}{7} or x > \frac{9}{7}

Interval Notation

(- \infty, \frac{9}{7}) \cup (\frac{9}{7}, \infty)

Solution steps

Find undefined (singularity) points:

x = \frac{9}{7}

The function domain

x < \frac{9}{7} or x > \frac{9}{7}

f (x) = \frac{x - 7}{x ^{2} - 2 x - 35}

f (x) = 7 (0)^{3} - 10

f (x) = 4 (\frac{1}{2})^{x}

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

g (t) = 9 + 8^{- t}

What is the domain of f(x)=(5x)/(7x-9) ?
The domain of f(x)=(5x)/(7x-9) is x< 9/7 \lor x> 9/7
