domain of f(x)=x|x|

Solution

domain

f (x) = x ∣ x ∣

Solution

- \infty < x < \infty

+1

Solution steps

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < x < \infty

Popular Examples

domain of f(x)= 5/(x^2+2x-10)domain

f (x) = \frac{5}{x ^{2} + 2 x - 10}

domain of f(x)=4x+2 domain

f (x) = 4 x + 2

domain of 2/3 x+3 domain

\frac{2}{3} x + 3

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

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

domain of f(x)=(x^2-x)/(sqrt(x^2-1))domain

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