domain of f(x)=-x^3+9x^2-20x

domain

f (x) = - x^{3} + 9 x^{2} - 20 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

ln (\frac{1}{x - 2})

3 x + y = - 6

f (x) = \frac{10}{x ^{2} - 7 x + 10}

f (x) = 7 - 6 x

7 x + 2 y = 24, (- 2, - 10)

What is the domain of f(x)=-x^3+9x^2-20x ?
The domain of f(x)=-x^3+9x^2-20x is -infinity <x<infinity
