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

domain

f (x) = \frac{( 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

f (x) = cot (\frac{π}{3} + 2 x)

3 x + 12

3 x + 10

f (x) = \frac{3 x + 5}{x ^{2} + 3 x - 28}

f (x) = x^{2} + 7

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