domain of f(x)=-x^2+8x-11

domain

f (x) = - x^{2} + 8 x - 11

- \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) = x + 1 + \frac{2}{x}

f (x) = 2 x^{2} - 3 x + 5

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

2 x^{2} - 8 x + 6

f (x) = \frac{2 x ^{2} + 3}{x ^{2} + x + 3}

What is the domain of f(x)=-x^2+8x-11 ?
The domain of f(x)=-x^2+8x-11 is -infinity <x<infinity
