domain of f(x)=(10-10x^2)/(x^2)

domain

f (x) = \frac{10 - 10 x ^{2}}{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

(5 x + 6) + (1 - 8 x) (x)

\frac{1}{3} x^{2} + 4

\frac{x + 3}{4 x + 3}

(x^{2} + 8 x) (x + 6)

f (x) = \frac{- 4 x ^{2}}{( x - 1 ) ( x + 1 )}

What is the domain of f(x)=(10-10x^2)/(x^2) ?
The domain of f(x)=(10-10x^2)/(x^2) is x<0\lor x>0
