Level:

Given a function \(f(x) = \frac{x} {3} + 1\), find the function \(g\) such that the graph of \(g\) is symmetric with the graph of \(f\) about the \(y\)-axis.

\(g\colon y = -\frac{x} {3} + 1\)

\(g\colon y = 3x + 1\)

\(g\colon y = -3x + 1\)

\(g\colon y = -\frac{x} {3} - 1\)

Such a function does not exist.
