Which function represents g(x), a reflection of f(x) = (3)x across the y-axis?
g(x) = 2(3)x
g(x) = −(3)x
g(x) = (3)−x
g(x) = 2(3)−x

Answer:

g(x)=-(3)x

Step-by-step explanation:

f(x) = 3x reflected over y- axis is f(x) = -3x

f(x) = 10x reflected over y- axis is f(x = -10x

To reflect across the y-axis, replace x by -x.

So, for f(x) = 3x, f(-x) = 3(-x), which simplifies to -3x.
