domain of f(x)=x^2-10x+21

domain

f (x) = x^{2} - 10 x + 21

- \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^{4} + 18 x^{2} + 81

f (X) = lo g_{3} (\frac{1}{9})

\frac{x ^{2} - 5 x + 4}{x + 1}

- x^{3} + 3 x^{2} + 10 x

f (x) = - 2 x + 4 - 1

What is the domain of f(x)=x^2-10x+21 ?
The domain of f(x)=x^2-10x+21 is -infinity <x<infinity
