To solve by completing the square, what needs to be moved in this equation? x2 = 9 - 4x

A. a = 4, b = 8, c= - 3

B. a = 4, b = - 8, c = - 3

C. a = 4, b = 8, c = 3

D. a = 4, b = - 8, c = 3

Asap describe the transformations required to obtain the graph of the function f(x) from the graph of the function g(x). f(x)=-5.8sin x. g(x)=sin x. a: vertical stretch by a factor of 5.8, reflection across y-axis. b: vertical stretch by a factor of 5.8,reflection across x-axis. c: horizontal stretch by a factor of 5.8, reflection across x-axis. d: horizontal stretch by a factor of 5.8 reflection across y-axis.
