domain of f(x)= 2/3 sqrt(x^2+1)^3

domain

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

- \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) = \frac{- 3}{5 x + 20} + 7

5 x + 13

5 x + 10

\frac{( 7 x + 1 ) 5 x}{10 x - 2}

ln (x - 1)
