Consider an object centred around A(2, 3). The object needs to be scaled down by a factor of 5 without changing its centre point’s position. Choose the correct order of transformations that should be applied to the object (T(x, y) is a translation with x, y, and S(x, y) is a scaling with factors x, y).
