Find the absolute extreme values of the function f(x)=|x-6| on the interval 3≤x≤10?
1) Absolute maximum is 4 at x=10; absolute minimum is 0 at x=6
2) Absolute maximum is -3 at x=3; absolute minimum is 0 at x=6
3) Absolute maximum is 4 at x=10; absolute minimum is -3 at x=3
4) Absolute maximum is 0 at x=6; absolute minimum is -3 at x=3
