domain of x^4-10x^2+9

domain

x^{4} - 10 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) = \frac{1}{2 x ^{2} - 5 x - 12}

f (x) = 3 tan (x), - π \leq x \leq π

3 x^{2} - 6 x

f (x) = \frac{18 x + 24}{x ^{2} + 5 x + 6}
