domain of (x^2-9)^2-9

domain

(x^{2} - 9)^{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) = (x + 7)^{5}

x^{3} - 6 x^{2} + 9 x

5 x + 1

f (x) = - 3 x^{2} - 6 x

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