domain of-x^6+7x^2+9x+12

domain

- x^{6} + 7 x^{2} + 9 x + 12

- \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{2}{x ^{2} - x - 2}

- 3 (x - 1)^{2} + 2

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

\frac{2 x ^{2} - 3 x}{x ^{2} - x - 12}

f (x) = \frac{4 x + 1}{x + 2}
