domain of f(x)=(x+4)/x

domain

f (x) = \frac{x + 4}{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{6 x ^{2} - x ^{4}}{9}

\frac{5}{x ^{2} - 1}

f (x) = 3^{x - 2} - 1

f (x) = - \frac{1}{2} \cdot lo g_{10} (- 2 - x) + 2

f (x) = \frac{4 - x}{∣ x ∣ - 1}
