The rule of a function changes from

f(x) = 6x^4 + 4 to g(x) = -3x^4 - 2
when two transformations are performed.

Which statement best describes how these transformations affect the graph of f(x)?

A. The graph is compressed by a factor of 1/2 and is reflected across the x-axis.
B. The graph is compressed by a factor of 1/2 and is reflected across the y-axis.
C. The graph is stretched by a factor of 1/2 and is reflected across the y-axis.
D. The graph is stretched by a factor of and is reflected across the x-axis.
