Let f(x)= e^x-x and g(x)=x^2-x, ∀ x ∈ R. Then the set of all x ∈ R, where the function h (x)=(f ° g)(x) is increasing, is:

Let $\displaystyle f(x)=\mathrm{e}^x-x$ and $\displaystyle g(x)=x^2-x, \forall x \in \mathbf{R}$. Then the set of all $\displaystyle x \in \mathbf{R}$, where the function $\displaystyle \mathrm{h}(x)=(f \circ g)(x)$ is increasing, is :
