Create a proportion using the form %/100 = to is/of represent the following word problem. Seven is what percent of 30?

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.

Can someone me and plz do the problem

If f(x) = 4x - 3 and g(x) = x + 4, find (f - g) (x)
