domain of f(x)=(x^2+5x+6)/(x^2+9)

domain

f (x) = \frac{x ^{2} + 5 x + 6}{x ^{2} + 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

f (x) = - 4 x + 20

4 x^{3} + x

lo g_{10} (x - 3) - 5

e^{t}
