# Math Help - intervals of increasing/ decreasing

1. ## intervals of increasing/ decreasing

for $f(x) = x^{1/3}$
increasing: (-∞, ∞)
Decreasing: ?
for decreasing i think its none. idk

2. What exactly is your function?

Did you mean $y=x^{\frac{1}{3}}$ ?

It will be increasing on $\frac{dy}{dx}>0$ and decreasing on $\frac{dy}{dx}<0$

I haven't learned that dy/dx stuff yet so that doesn't make sense to me right now. And yes its $f(x)= x^{1/3}$
for $f(x) = x^{1/3}$
