(2a) g(x) = f(x) - 5
So it involves shifting the curve downward by 5 units.
(2b) g(x) = f(x - 8)
So it involves shifting the curve to the right by 8 units.
(3a) The transformation is "Reflection about the x-axis"
(2, 4) is transformed to (2, -4)
(3b) The transformation is "Shift down by 2 units"
(2, -1) is transformed to (2, -3)
