domain of f(x)=(10)/(4-x)

domain

f (x) = \frac{10}{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

f (x) = \frac{24}{x + 3}

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

f (x) = - cos (4 x)

f (x) = 4 x^{2} + 2

f (x) = \frac{4 x ^{2} - 9}{4 x ^{2} - 4 x - 3}

What is the domain of f(x)=(10)/(4-x) ?
The domain of f(x)=(10)/(4-x) is x<4\lor x>4
