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^{2} + 10 x + 28

f (x) = x^{2} + 10 x + 29

y = \frac{8 - x}{x ^{2} + 6 x}

f (x) = x - 13 + x + 12

f (x) = \frac{3 x - 5}{x ^{2} + 8 x + 7}

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