domain of f(x)=(2x)/(x-3)

domain

f (x) = \frac{2 x}{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

(1664 - 64 y^{2}) y^{2}

f (x) = \frac{x - 1}{x + 5}

x^{\frac{7}{2}} - 4 x^{2}

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

(3, 2), (- 4, - 1)

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