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

domain

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

- \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 ^{2} - 2 x - 3}{x}

f (x) = \frac{x ^{2} - 2 x - 8}{x}

(- 5, 2), (1, - 3)

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

f (x) = x (x + 11) (x - 6)
