domain of f(x)=(2x+5)/(x-3)

domain

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

x (x + 3)^{\frac{2}{5}}

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

f (x) = 9 x - x^{3}

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

12 x^{3} - 5 x^{2} - 11 x + 6

What is the domain of f(x)=(2x+5)/(x-3) ?
The domain of f(x)=(2x+5)/(x-3) is x<3\lor x>3
