domain of x^3+3x^2+3x+1

domain

x^{3} + 3 x^{2} + 3 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{12 x}{( x ^{2} - 4 ) ^{2}}

f (x) = \frac{x}{x ^{2} + 15 x + 54}

y = x^{4}

∣ 2 - 5 x ∣

f (z) = e^{\frac{1}{z - 1}}
