For the function f(x) = 3x^3 + 5x, give a formula for the following functions.
\n" ); document.write( "f(-x) = ?
\n" ); document.write( "-f(x) = ?
\n" ); document.write( "solution
\n" ); document.write( "f(x) = 3x^3 + 5x
\n" ); document.write( "f(-x) = 3(-x)^3+5(-x)
\n" ); document.write( "you have not asked this
\n" ); document.write( "f-(-x)=f(x) as both negative convert to positive
\n" ); document.write( "f-(-x)= f(x)=3x^3 + 5x,
\n" ); document.write( "=3*-x^3-5x=-3^3-5x both term convert to negative as index (power on variable ) is odd
\n" ); document.write( "-f(x) = -(3x^3 + 5x)=-3x^3 -5x here also both term convert to negative due to change 0f sign to entire function . it is not always f(-x) = -f(x)
\n" ); document.write( "f-(-x)=3x^3 + 5x, \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
