domain of f(x)=(120+4x)/x

domain

f (x) = \frac{120 + 4 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{x + 5}{15 + x ^{2} - 64}

(- 5, 1), (7, 8)

f (x) = 4 - 6 x^{2}

\frac{x ( x + 5 )}{7}

x

What is the domain of f(x)=(120+4x)/x ?
