domain of (2/x)/(4/(x+4))

domain

\frac{\frac{2}{x}}{\frac{4}{x + 4}}

x < - 4 or - 4 < x < 0 or x > 0

Interval Notation

(- \infty, - 4) \cup (- 4, 0) \cup (0, \infty)

Solution steps

Find undefined (singularity) points:

x = 0, x = - 4

The function domain

x < - 4 or - 4 < x < 0 or x > 0

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

3 w (2 - 3 u) = 6 u - 3

∣ - 19 + 6 x ∣

f (x) = \frac{- 4 x - 7}{7 x - 3}

\frac{( 7 x + 2 )}{- 3 + 5 x}
