\n" ); document.write( "I have no idea how the instructor is coming up with 238 on the answer key. The problem is; Use the Remainder theorem to evaluate T(x)=3x^4-x^2 + 4, when x=-3. He does not give a lesson this. The lesson he gave is P(x) etc, etc..., there is no T(x) in our book or in his lessons. There are going to be more of these on the test. What is the T(x) and how do I do it?

\n" ); document.write( "\n" ); document.write( "to evaluate \"T%28x%29=3x%5E4-x%5E2+%2B+4\" when \"x=-3+\" just substitute \"-3\" for \"x\" in\r
\n" ); document.write( "\n" ); document.write( " \"T%28x%29=3x%5E4-x%5E2+%2B+4\"\r
\n" ); document.write( "\n" ); document.write( " \"T%28-3%29=3%28-3%29%5E4-%28-3%29%5E2+%2B+4\"............\r
\n" ); document.write( "\n" ); document.write( "\"T%28-3%29=243%2B+4-9+\"\r
\n" ); document.write( "\n" ); document.write( "\"T%28-3%29=247-9+\"\r
\n" ); document.write( "\n" ); document.write( "\"T%28-3%29=238+\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "What is the T(x)? It is just symbol for a function (a functional symbol), you can name it how do you want.\r
\n" ); document.write( "\n" ); document.write( "T(x), or P(x), or f(x), or g(x), are used to name a functions, all are same as \"y\"; recall \"y=ax%5E2%2Bbx%2Bc\"\r
\n" ); document.write( "\n" ); document.write( "you can use any functional symbol from above:\r
\n" ); document.write( "\n" ); document.write( "so, \"y=ax%5E2%2Bbx%2Bc\" is same as \"f%28x%29=ax%5E2%2Bbx%2Bc\",\"T%28x%29=ax%5E2%2Bbx%2Bc\", \"P%28x%29=ax%5E2%2Bbx%2Bc\", or \"g%28x%29=ax%5E2%2Bbx%2Bc\" \r
