Reflecting over the x-axis involves multiplying all y-coordinates by -1: A(-4, -2), B(-2, -3), C(0, -2).Dilating by a scale factor of 2 doubles all coordinates: A(-8, -4), B(-4, -6), C(0, -4).
Do you have the math exercices? I am sorry but I can just help in the subjects concerning math. It is been some time since I studied biology and other high-school subjects.
