f[x_] := x^2 - 4 x + 3;

Plot[{f[x], f[x] Boole[1 < x < 3]},
 {x, 0, 4}, Filling -> {2 -> Axis}]

or

Plot[{f[x], f[x] Boole[1 < x < 3]},
 {x, 0, 4}, Filling -> {2 -> 0}]

Hi,

I'm trying to only fill the area under a function from one x-value
(x_1) to another x-value (x_2) (the purpose is to represent an
integral with the filling) . I'm using the Filling -> Axis option, but
I'm not sure how to limit the x-values.

Do you guys know anything about this?
