    Find the limits

    f(x)=2X+8

    lim f(x)
    x->2
    __________________________________________________ ___________

    f(x)={ 3x, x<=1
    x+1, x > 1

    lim f(x)
    x->1

    Thank you

    f(x)=2X+8
    lim f(2) = 2(2) + 8 = 12 (ans)
    x->2
    ------------------------------
    f(x)={ 3x, x<=1
    -------x+1, x > 1
    lim f(x)
    x->1
    My take is that f(x) has no limit as this is a double sided limit problem.

    Hope it helps
