domain of f(x)=3x^{2/5}

domain

f (x) = 3 x^{\frac{2}{5}}

- \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{1}{3} x^{3} + \frac{2}{5} x + 1

ln (3 x + 12)

f (x) = \frac{1}{( x + 5 ) ^{2}}

f (x) = lo g_{10} (80 - 0.5 x)

f (x) = lo g_{5} (x^{2} + 16)
