domain of f(x)=x^2-2x-5

domain

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

- \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

d o main f (x) = \frac{x}{x ^{2} - 4 x + 3}

in v erse f (x) = x - 3

in v erse 1 - x + 2

r an g e 2 x^{2} - x - 6

in t erce pt s f (x) = x^{3} - 64 x

What is the domain of f(x)=x^2-2x-5 ?
The domain of f(x)=x^2-2x-5 is -infinity <x<infinity
