domain of f(x)=(-4x)/(sqrt(x^2+2))

domain

f (x) = \frac{- 4 x}{x ^{2} + 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

f (x) = 3 x^{2} - 2 x

f (x) = \frac{x}{x - 6}

f (x) = lo g_{10} (2 x - 4)

f (x) = 3 + 6 x - 3

\frac{( x ^{3} )}{( 4 x ^{2} + 17 x - 15 )}
