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

domain

g (x) = \frac{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

f (x) = 3 x + 21

f (x) = \frac{x - 4}{3}

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

\frac{1}{x + 3}

- 3 x^{2} - 12 x - 5

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