domain of f(x)=x^2+1x-3

domain

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

- \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

3 x

f (x) = cos (\frac{1}{x})

- 4 x + 5

f (x) = \frac{x - 2}{4 - x}

f (x) = x^{2} + 5 x + 4

What is the domain of f(x)=x^2+1x-3 ?
The domain of f(x)=x^2+1x-3 is -infinity <x<infinity
