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

domain

f (x) = x^{2} + 6 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

- 9 x + 3 y = - 6

8 - 9 x^{2}

(9, 1), (2, 11)

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

\frac{1}{7} x^{2}
