domain of f(x)=9x^7+21x^6-30x^5-19

domain

f (x) = 9 x^{7} + 21 x^{6} - 30 x^{5} - 19

- \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

- 3 sin (- 2 x + \frac{π}{2})

f (x) = - 3 (x + 1)^{2} + 4

f (x) = 5 x + 4 x - 9

f (x) = \frac{10 + x}{- 6 + 2 x}

x^{2} - 2 x - 3
