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

domain

y = \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

8 x^{4} - 14 x^{3} - 9 x^{2} + 11 x - 1

6 x^{3} - 5 x^{2} - 6 x

lo g_{10} (x^{2} - 9)

\frac{x + 7}{x - 2}

(3 + x)^{2}

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