domain of f(x)=(x^2-1)/(x-2)

domain

f (x) = \frac{x ^{2} - 1}{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

f (x) = 4 x^{4}

f (x) = (x + 1)^{2} - 4

f (x) = x^{3} - 4 x^{2} - 16 x + 9

y = lo g_{5} (x) - 9

(4, 11), (9, 26)

What is the domain of f(x)=(x^2-1)/(x-2) ?
The domain of f(x)=(x^2-1)/(x-2) is x<2\lor x>2
