domain of (x^2-4)/(x-2)

domain

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

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

y = 2 x

x^{2} + 7 x

f (x) = 2 x y - 4 x + 6 y - 3 = 0

4 x + y + 5 = 0

x + 3 y = 0

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