domain of f(x)=2x(2x^2+8x)

domain

f (x) = 2 x (2 x^{2} + 8 x)

- \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{3 x}{x - 2}

f (x) = x^{2} - 1

x^{3} - 6

y = 6 x + 1, (- 7, 1)

8 x + 4
