domain of (1+4x)/(x-1)

domain

\frac{1 + 4 x}{x - 1}

x < 1 or x > 1

Interval Notation

(- \infty, 1) \cup (1, \infty)

Solution steps

Find undefined (singularity) points:

x = 1

The function domain

x < 1 or x > 1

f (x) = \frac{2 x - 1}{4 x + 3}

f (x) = (e^{- x})

h (x) = 3 x + 4 + 5

3 \frac{x - 1}{3}

f (x) = \frac{2 x + 4}{x ^{2} + 7 x + 10}
