Graph f(x) = x + 2(x - 3) then use the graph to evaluate lim x->2 x + 2(x - 3)

    so f(x)= 3x - 6. or y=3x-6. take any 3 values of x and find values of y for them. plot and join the points on the cartesian plane and you have the graph which is a straight line.

    well you just have to find the value of f(x) for x=2. thats all it means.

    Look on the graph at x = 2 and read off the value of y.
