You can put this solution on YOUR website!
a. f(0) = 6 [all the terms containing an x are canceled out]\r
\n" ); document.write( "\n" ); document.write( "b. f(2) = 3(2)^5 - 5(2)^3 + 2(2)^2 + 6
\n" ); document.write( " = 3(32) - 5(8) + 2(4) + 6
\n" ); document.write( " = 96 - 40 + 8 + 6
\n" ); document.write( " = 70\r
\n" ); document.write( "\n" ); document.write( "c. f(-2) = 3(-2)^5 - 5(-2)^3 + 2(-2)^2 + 6
\n" ); document.write( " = 3(-32) - 5(-8) + 2(4) + 6
\n" ); document.write( " = -96 + 40 + 8 + 6
\n" ); document.write( " = -42\r
