domain of f(x)= 2/(2-7x)

domain

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

x < \frac{2}{7} or x > \frac{2}{7}

Interval Notation

(- \infty, \frac{2}{7}) \cup (\frac{2}{7}, \infty)

Solution steps

Find undefined (singularity) points:

x = \frac{2}{7}

The function domain

x < \frac{2}{7} or x > \frac{2}{7}

f (x) = (x - 1)^{2} (x - 2)^{3}

- 7 x - 2 y = 14

\frac{x + 2}{x - 2}

f (x) = \frac{( x ^{3} )}{( x - 1 ) ^{2}}

f (x) = - x^{3} + 9 x^{2} - 55

What is the domain of f(x)= 2/(2-7x) ?
The domain of f(x)= 2/(2-7x) is x< 2/7 \lor x> 2/7
