domain of f(x)= 2/(4-x)

domain

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

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

2 cos (\frac{1}{4}) y - 3

x ln (x^{2})

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

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

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

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