domain of f(x)= 1/(7x)

domain

f (x) = \frac{1}{7 x}

x < 0 or x > 0

Interval Notation

(- \infty, 0) \cup (0, \infty)

Solution steps

Find undefined (singularity) points:

x = 0

The function domain

x < 0 or x > 0

d o main f (x) = 9 x + 36

am pl i t u d e 2 + sin (4 x)

in v erse f (x) = \frac{8 x - 1}{2 x + 9}

a sy m pt o t es f (x) = \frac{x ^{2} - 49}{x}

in v erse f (x) = - \frac{1}{2}
