Which equation represents new equation from the parent function after the following transformations? f(x) is translated right 2 and down 1 followed by a
reflection in the x axis and then a horizontal shrink of 1/2.
g(x) = (-2x + 2)^2 - 1
g(x) = - (1/2 x - 2)^2 + 1
g(x) = 2(2x - 2)^2-1
g(x) = - (2x - 2)^2 + 1
