  <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(g(x))=
     4 \, g\left(-2\right) - 2 \, g'\left(-4\right) 
                \hspace{1em} \text{and} \hspace{1em} T(g(x))=
     3 \, g'\left(x\right) - 4 </me>
    Explain why one these maps is a linear transformation and why the other map is not.
    </p>
  </statement>
  <answer>
    <p><m>S</m> is linear and <m>T</m> is not linear.</p>
