domain of x^2-2x-8

domain

x^{2} - 2 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) = 16 x^{5} - 12 x^{3} + 4 x^{2} - 3

f (x) = \frac{x}{8} - 3

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

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