c)reflect across the x-axis translate 2 units to the left translate down 2 units stretch by the factor 2
d)reflect across the x-axis translate 2 units to the right translate up 2 units stretch by the factor 2

Can someone please help me, not sure how to do this problem.

    Technically, the stretching is done before the translation. Otherwise the coordinates of the vertex would also be scaled.
