domain of f(x)=(x^2+2x+1)/(x-3)

domain

f (x) = \frac{x ^{2} + 2 x + 1}{x - 3}

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

(- 2.4) (13.1)

\frac{x ^{2}}{2} + \frac{1}{x}

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

f (x) = x^{4} - 50 x^{2} + 8

y = x^{2} + 2 x - 8

What is the domain of f(x)=(x^2+2x+1)/(x-3) ?
The domain of f(x)=(x^2+2x+1)/(x-3) is x<3\lor x>3
