domain of (x^2-16)/(x-4)

domain

\frac{x ^{2} - 16}{x - 4}

x < 4 or x > 4

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 4

The function domain

x < 4 or x > 4

f (x) = (8 x)

ln (\frac{( x - 1 )}{x ^{2} - 4})

f (x) = \frac{1}{x ^{2} - 8 x + 18}

f (x) = (x + 7)^{2}

2 x^{2} - x - 1

What is the domain of (x^2-16)/(x-4) ?
The domain of (x^2-16)/(x-4) is x<4\lor x>4
