Answer:
Reflection through the y-axis, f(x) → f(-x). Option B is correct
Explanations:
Reflected images are mirror images of each other.
If the parent function f(x) is reflected over the y-axis, the resulting function will be f(-x). Note that only the x-values (dependent variable) are negated for a reflection over the y-axis.
From the given graph, you can see that both lines have equal but opposite slope and are mirror images of each other. Since the lines intersects along the y-axis, hence we can conclude that the description of how the dotted line relates to the solid line (f(x)) is reflection through the y-axis, f(x) → f(-x)
