domain of f(x)=(-9-3x)/(7x-5)

domain

f (x) = \frac{- 9 - 3 x}{7 x - 5}

x < \frac{5}{7} or x > \frac{5}{7}

Interval Notation

(- \infty, \frac{5}{7}) \cup (\frac{5}{7}, \infty)

Solution steps

Find undefined (singularity) points:

x = \frac{5}{7}

The function domain

x < \frac{5}{7} or x > \frac{5}{7}

lo g_{2} (x + 2) + 3

\frac{2 x}{3 - 2 x}

f (x) = x^{2} - 4, - 1 < x \leq 3

f (x) = x - 2 + \frac{1}{1 - x}

f (x) = \frac{5 x - 4}{9 x + 8}

What is the domain of f(x)=(-9-3x)/(7x-5) ?
The domain of f(x)=(-9-3x)/(7x-5) is x< 5/7 \lor x> 5/7
