    log graphs

    sketch on separate diagrams the graphs of y= In x and of y = | In x|
    Calculate correct decimal places the values of x for which | In x| = 3
    on the graph y= | In x| ,sketch also the graph y=3-x; hence deduce how
    many solutions there are of equation | In x| + x = 3.


    thanks all thanks
