    \[\lim_{x \rightarrow 2}f(x)+g(x)=f(2)+g(2)\] can u find f(2) and g(2) ?

    nopes, see the graph, when x=2, y=f(x)= 2 ok?

    oh, wait, i think the dot is shaded to make the value of f(2) as 1. and not 2 so f(2)=1 as u correctly said before.

    but g(2) is 0 isn't it? so, 1+0=1 is the value of limit, ok?

    thats because when x=2,g(x) is on x-axis, so g(2)=0

    f(x)=0 and because its multiplying the total limit is 0

    right,because f(0)=0
