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

domain

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

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

f (x) = 8 x + 5

y = x^{2} - 4 x + 4

3 x^{4} - 16 x^{3} + 18 x^{2}

f (x) = 2 (x - 1) (x + 2) (x - 3)

What is the domain of f(x)=(7x-3)/(7x) ?
The domain of f(x)=(7x-3)/(7x) is x<0\lor x>0
