The function rule for g(x) can be found by reflecting f(x) in the -axis. The reflection in the -axis essentially flips the function upside down.
So if f(x) = x, then g(x) would be the function where every y-coordinate is the negative of f(x).
Thus, the function rule for g(x) would be g(x) = -x.
Write the function rule for the function shown below reflected in the given axis.
f(x)x; -axis
Let g(x) be the reflection of f(x) in the -axis. What is the function rule for g(x)?
