To understand the relationship between the functions \( f(x) \) and \( g(x) \), notice that \( g(x) \) modifies \( f(x) \) by applying a vertical translation and a vertical compression. The original function \( f(x) = 9x \) is adjusted by scaling down its output by a factor of \( \frac{9}{10} \) and then translating it downward by 7 units. Thus, the correct choice among the options provided is C: First there is a vertical translation down 7 units. This option captures the transformation after the initial vertical compression, which is implied when viewing how \( g(x) \) is derived from \( f(x) \).
