domain of f(x)=(-20)/(x-8)

domain

f (x) = \frac{- 20}{x - 8}

x < 8 or x > 8

Interval Notation

(- \infty, 8) \cup (8, \infty)

Solution steps

Find undefined (singularity) points:

x = 8

The function domain

x < 8 or x > 8

y = \frac{2}{\frac{13}{x} + 3}

f (x) = \frac{6 x - x ^{2}}{x ^{2} + 4 x - 12}

\frac{( x - 1 ) ( x + 4 )}{( x + 1 ) ( x - 5 )}

y = \frac{1}{1 - sin ( x )}

1.5 x^{2} - x + 3.7

What is the domain of f(x)=(-20)/(x-8) ?
The domain of f(x)=(-20)/(x-8) is x<8\lor x>8
