domain of f(x)=x^2-9x

domain

f (x) = x^{2} - 9 x

- \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) = 12 x^{2} + 8 x - 15

f (x) = 0

f (x) = \frac{x ^{2}}{5 - x}

f (x) = 7 x + 2

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

What is the domain of f(x)=x^2-9x ?
The domain of f(x)=x^2-9x is -infinity <x<infinity
