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

domain

f (x) = 8 - 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) = 3^{x + 3}

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

f (x) = 2 cos (x)

f (x) = 15 - 2 x - x^{2}

f (x) = 3 x^{2} + 12 x + 20
