domain of f(x)=(x-7)/(x^2)

domain

f (x) = \frac{x - 7}{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

(6, 5), (- 2, 5)

x^{2} - 2 x + 7

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

f (x) = (x + 8)^{8}

f (x) = - x^{2} - 5

What is the domain of f(x)=(x-7)/(x^2) ?
The domain of f(x)=(x-7)/(x^2) is x<0\lor x>0
