domain of f(x)=3x^2+(1/(x^2+5))+2

domain

f (x) = 3 x^{2} + (\frac{1}{x ^{2} + 5}) + 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 + 2 ∣}{x + 2}

f (x) = 5 + x - 3

\frac{( x - 20 )}{- 0.25}

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

f (x) = \frac{12 - 3 x ^{2}}{x - 3}
