domain of f(x)=3x^2-4

domain

f (x) = 3 x^{2} - 4

- \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

\frac{4 x}{x - 2}

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

f (x) = \frac{2 x + 3}{5 - x}

\frac{- 2 x ^{3} + 9 x ^{2} - 27}{3 x ^{2} - 9}

f (x) = 4 x^{2} + 4 x + 1
