domain of f(x)= 1/(3-x)

domain

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

x < 3 or x > 3

Interval Notation

(- \infty, 3) \cup (3, \infty)

Solution steps

Find undefined (singularity) points:

x = 3

The function domain

x < 3 or x > 3

f (x) = x^{2} + 3, x \leq 0

f (x) = \frac{x ^{2} + 6 x - 16}{x ^{2} - 4}

x^{2} - 4 x + 8

f (x) = \frac{7 x ^{2} + 16}{x ^{2} - 16}

What is the domain of f(x)= 1/(3-x) ?
The domain of f(x)= 1/(3-x) is x<3\lor x>3
