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

domain

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

(- 1.2) (- 9.4)

f (x) = \frac{x}{x ^{2} - 16}

f (x) = \frac{7}{x ^{8} + 5 x + 1}

(10, - 1), (- 4, - 5)
