How to make a function handle of another function handle?

As input for my function file I have a function handle, for example y = @(x)x.^3. In this function file this function is evaluated, however I also want to integrate the absolute value of this function. The MATLAB command integral requires a function handle: integral(@(x)y,LB,UB). How do I take the absolute value of this function handle? I tried: @(x)abs(y), but this didn't work. Also some other things I tried didn't work, except filling in @(x)abs(x.^3), but this is not what I want, because the function handle should remain an input for the function file.

@(x) abs(y(x)) Because yo need variable x to be part of the expression of your new anonymous function. Taking y(x) then take the absolute value of that.
