domain of f(x)=(9x)/(1+x^2)

domain

f (x) = \frac{9 x}{1 + x ^{2}}

- \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) = - 2 x^{2} + 8

3 x + 7

\frac{1}{x + 2 - 2}

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

2 lo g_{10} (x - 2)
