domain of f(x)=x^3-3x^2+7x+1

domain

f (x) = x^{3} - 3 x^{2} + 7 x + 1

- \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) = \frac{x}{3}

f (x) = \frac{x ^{3} + x ^{2} + x + 1}{∣ x + 1 ∣}

x^{3} - 3 x^{2} + 1

f (x) = \frac{3 x}{x + 1}

f (x) = \frac{1}{- x ^{2} + 5 x}

What is the domain of f(x)=x^3-3x^2+7x+1 ?
The domain of f(x)=x^3-3x^2+7x+1 is -infinity <x<infinity
