Help me pleas asap in explain

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.

If y varies directly as x2 and y=6 when x=6, find the constant of variation.

Solve each quadratic equation by factoring and using the zero product property. n^2 - 49 = 0
