domain of f(x)=x^3-4x+8

domain

f (x) = x^{3} - 4 x + 8

- \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 + 6)^{2} + 8

f (x) = x^{3} + 10

y = - 3 x

f (x) = - x^{3} + 12 x - 16

- x + 3
