domain of f(x)=sqrt(4x^2)

domain

f (x) = 4 x^{2}

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

Find non-negative values for radicals:

- \infty < x < \infty

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

- \infty < x < \infty

\frac{x - 4}{x - 6}

ln (x + 2) (x - 1)^{2}

\frac{x - 4}{x - 9}

y + 2

y + 1
