    now, we have these natural limits: \[\Large - \frac{4}{5} \leqslant \left( {\frac{4}{5}\sin x} \right) \leqslant \frac{4}{5}\]

    your part of graph is enclosed in this segment: \[\Large \left[ { - \frac{4}{5},0} \right]\]

    As you can see from my drawing, the requested range is the interval: \[\Large \left[ { - \frac{4}{5},0} \right]\]
