domain of f(x)=(x)^{-1}= x/(7x-2)

domain

f (x) = (x)^{- 1} = \frac{x}{7 x - 2}

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) = 3 e^{- 4 x}

f (p) = 280000 - 35 p

f (x) = \frac{x ^{2}}{100} + \frac{y ^{2}}{32} = 1

f (x) = 5 - 4 x + 7 x

f (x) = \frac{- 5 x - 3}{4 x - 2}

What is the domain of f(x)=(x)^{-1}= x/(7x-2) ?
The domain of f(x)=(x)^{-1}= x/(7x-2) is x< 2/7 \lor x> 2/7
