a) f(x) = 3x +4
\n" ); document.write( "this function is 1-1 with domain and range the real numbers, R
\n" ); document.write( "the graph confirms each member in the domian is associated with a unique member in the range
\n" ); document.write( "\"+graph%28+300%2C+200%2C+-10%2C+10%2C+-10%2C+10%2C+3x%2B4%29+\"
\n" ); document.write( "b) y = 3x+4
\n" ); document.write( "x = (y-4) / 3
\n" ); document.write( "now interchange the x and y
\n" ); document.write( "y = (x-4) / 3
\n" ); document.write( "f'(x) = (x-4) / 3
\n" ); document.write( "
\n" ); document.write( "
