domain of f(x)=(3x+9)/5

domain

f (x) = \frac{3 x + 9}{5}

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < x < \infty

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

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

\frac{x - 3}{x ^{2} - 9}

y = \frac{1}{- 4 x ^{2} - 20 x - 21}

f (x) = \frac{x + 6}{x - 8}

What is the domain of f(x)=(3x+9)/5 ?
The domain of f(x)=(3x+9)/5 is -infinity <x<infinity
