domain of f(x)=(9-x^2)/(2x^2)

domain

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

x^{4} - x^{3} - 13 x^{2} + 25 x - 12

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

f (x) = (9 - x^{2}) (x + 1)

(- 8, - 3), (2, 3)

f (x) = \frac{14}{1 + 3 ^{- x}}

What is the domain of f(x)=(9-x^2)/(2x^2) ?
The domain of f(x)=(9-x^2)/(2x^2) is x<0\lor x>0
