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) = sin (x) + 3 cos (x)

y = (2 x + 3)^{2}

cos (arccos (x))

f (x) = 6 x^{5} + 33 x^{4} - 30 x^{3} + 100

f (x) = x^{4} + 2 x^{2} - 3

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