domain of f(x)=4x^2+12x+9

domain

f (x) = 4 x^{2} + 12 x + 9

- \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{1}{2 x 3 + ln ( x )}

\frac{x ^{2} + 5 x + 6}{x ^{2} - 4}

f (x) = 3 - 2 x - 4

- 3 x + 9

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