domain of f(x)=3x^2+15x+18

domain

f (x) = 3 x^{2} + 15 x + 18

- \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

- 3 tan (3 x + π)

\frac{x + 4}{x ^{2} + x - 3}

f (x) = 3 x^{2} + 15 x + 10

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

f (x) = \frac{x ^{2} + 2 x - 8}{x ^{2} - x - 2}

What is the domain of f(x)=3x^2+15x+18 ?
The domain of f(x)=3x^2+15x+18 is -infinity <x<infinity
