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

domain

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

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

\frac{11250 + 180 x ^{2}}{x}

f (x) = \frac{x - 8}{2 x + 7}

\frac{5}{3} x - 5

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

f (x) = \frac{4 x - 5}{1 + 2 x}

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