domain of f(x)=5x^4+40x^3-x^2-8x

domain

f (x) = 5 x^{4} + 40 x^{3} - 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) = 5 (x + 4)^{2} - 1

f (x) = \frac{1}{x ^{2} + 1}

(5.6), (1.3)

f (x) = ln (x^{2} - 12 x)

f (x) = x^{4} - 12 x^{3}
