The graph of f(x) is obtained by reflecting the graph of g(x)=3|x| over the x-axis.
Alinara [238K]

Answer:

Choice B), f(x) = -3|x|.

Step-by-step explanation:

Each point on the graph of g(x) can be represented as (x, g(x)).

When the graph of g(x) is reflected over the x-axis, each point on the graph is also reflected over the x-axis. The x-coordinate of each point will not change but the sign in front of the y-coordinate will flip. For example, 1 (same as +1) will become -1, and vice versa. In general, (x, g(x)) will become (x, -g(x)).

On the other hand, points on the graph of f(x) can be represented as (x, f(x)). f(x) is the reflection of g(x), so (x, -g(x)) and (x, f(x)) shall be equivalent. In other words,

f(x) = -g(x) = - 3|x|.
