You can put this solution on YOUR website!
y = (x-1)*e^x
\n" ); document.write( "Take y' using the product rule and we get
\n" ); document.write( "y' = (x-1)*e^x + e^x (1)
\n" ); document.write( "take y''using the product rule and we get
\n" ); document.write( "y'' = (x-1)*e^x + e^x + e^x
\n" ); document.write( "Now y''(0) = (0-1)e^0 + e^0 + e^0 = -1 + 1 + 1 = 1
\n" ); document.write( "This is answer choice (D)
\n" ); document.write( "
\n" );
