Which describes the difference between the graph of f(x) = x2 and g(x) = -(x2 - 2)?

a)
the graph of f(x) is obtained by flipping g(x) over the x-axis and shifting up 2 units.
b)
the graph of g(x) is obtained by flipping f(x) over the x-axis and shifting up 2 units.
c)
the graph of f(x) is obtained by flipping g(x) over the x-axis and shifting left 2 units.
d)
the graph of g(x) is obtained by flipping f(x) over the x-axis and shifting left 2 units.

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 25002500 grams and a standard deviation of 800800 grams while babies born after a gestation period of 40 weeks have a mean weight of 27002700 grams and a standard deviation of 385385 grams. if a 3232-week gestation period baby weighs 21252125 grams and a 4040-week gestation period baby weighs 23252325 grams, find the corresponding z-scores. which baby weighs lessless relative to the gestation period?
