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

domain

f (x) = 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) = \frac{x - 7}{x + 6}

y = 3 x + 1, (6, 9)

f (x) = (x^{2} - 1)^{\frac{1}{5}}

f (x) = 7 - x

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