Write a rule for g described by the transformations of the graph of f.
7. f(x) = x²; a reflection in the x-axis, a vertical stretch by a factor of 2, and a translation 3 units down
8. f(x) = x²; a vertical shrink by a factor of, and a translation 3 units left
9. f(x) = x²; a reflection in the x-axis, and a translation 3 units up
10. f(x) = x²; a translation 3 units right, and a reflection in the x-axis
for down
