domain of f(x)=(-2x^2+8x-4)/(x^2)

domain

f (x) = \frac{- 2 x ^{2} + 8 x - 4}{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

\frac{( 2 x + 3 )}{( 5 x - 1 ) x - 2}

x + a

f (x) = \frac{2}{3} lo g_{10} (- 4 (x - 12) + 3)

8 t - 32

f (x) = \frac{x - 9}{x ^{2} - 2 x - 63}

What is the domain of f(x)=(-2x^2+8x-4)/(x^2) ?
The domain of f(x)=(-2x^2+8x-4)/(x^2) is x<0\lor x>0
