domain of f(x)=(x+8)/(2-x)

domain

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

x < 2 or x > 2

Interval Notation

(- \infty, 2) \cup (2, \infty)

Solution steps

Find undefined (singularity) points:

x = 2

The function domain

x < 2 or x > 2

f (x) = 40 x - 4 x^{2}

x^{3} - 4 x

f (x) = \frac{30}{7} - \frac{3}{7} x

x - 5 x^{\frac{1}{5}}

x - 2 y = 5

What is the domain of f(x)=(x+8)/(2-x) ?
The domain of f(x)=(x+8)/(2-x) is x<2\lor x>2
