domain of f(x)=(x-7)/(5x^2)

domain

f (x) = \frac{x - 7}{5 x ^{2}}

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{3 x - 9}{x ^{2} - 6 x + 9}

f (x) = \frac{3}{5} x - 12

\frac{2 x ^{2} + 16 x - 18}{x ^{2} + x - 6}

3 cos (x - \frac{π}{4}) - 1

f (x) = x^{4} - 50 x^{2} + 4

What is the domain of f(x)=(x-7)/(5x^2) ?
The domain of f(x)=(x-7)/(5x^2) is x<0\lor x>0
