    @GaLm does the light of the night depend on the shutter speed or the shutter speed depend of the light conditions? :)

    " a function of" means it "depends on" Example: when you go to the grocery store, the total bill at check-out is "a function of" what you bought.

    Mathematically, it is expressed as: f(x) means function f is a function of x (the independent variable). x is usually plotted on the x-axis.
