domain of f(x)= 1/(x^2)+3

domain

f (x) = \frac{1}{x ^{2}} + 3

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) = 1 + e^{(\frac{x ^{2}}{∣ x ∣ - 2})}

g (x) = 6 - \frac{1}{x ^{2}}

f (x) = \frac{9}{x - 13} + \frac{3}{x - 2}

(x + 5) - (x^{2} + 8 x)

f (x) = \frac{( x + 4 )}{x ^{2} + 5 x}

What is the domain of f(x)= 1/(x^2)+3 ?
The domain of f(x)= 1/(x^2)+3 is x<0\lor x>0
