find the integration of absolute x from -4 to 2? could anyone show me the way to get 10?
thanks

    integrate x from 0 to +4 to get the absolute value when x is negative
    add that to the integral from 0 to 2.
    first part
    4^2/2 - 0^2/2 = 8
    second part
    2^2/2 - 0^2/2 = 2
    8+2 = 10
