domain of f(x)=2x^2-6x-8

domain

f (x) = 2 x^{2} - 6 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) = (2 x)^{3} - 3

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

f (x) = \frac{x}{x - 9}

\frac{3}{2 x - 3}

\frac{x - 4}{x ^{3} - 5 x ^{2} + 12 x - 33}

What is the domain of f(x)=2x^2-6x-8 ?
The domain of f(x)=2x^2-6x-8 is -infinity <x<infinity
