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

domain

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

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) = \frac{5 x + 8}{3 x - 5}

f (x) = \frac{4 x ^{2} - 9}{x ^{2} - 25}

- x + 9 x - 20

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

4^{x} + 3 \cdot 2^{x} + 1

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