  <statement>
    <p>
        Consider the following maps of polynomials <m>S:\mathcal{P}\rightarrow\mathcal{P}</m>
        and <m>T:\mathcal{P}\rightarrow\mathcal{P}</m> defined by
        <me>
            S(f(x))=
                    -4 \, x f\left(x\right) + 2 \, f\left(2\right)
                \hspace{1em} \text{and} \hspace{1em}
            T(f(x))=
                    -4 \, f'\left(-3\right) - 2
        </me>
        Explain why one these maps is a linear transformation and why the other map is not.
