If the graph of f is decreasing on [0,infinity)the what can be said about the graph of y=f(-x)+1? The graph of y=-f(x)-1?
\n" ); document.write( "-----------------------------------------
\n" ); document.write( "f(-x) + 1 is a reflection in the y-axis and a +1 vertical shift.
\n" ); document.write( "---
\n" ); document.write( "If f(x) is decreasing to the right of the y-axis
\n" ); document.write( "f(-x) will be increasing to the left of the y-axis.
\n" ); document.write( "The +1 will move all points 1 unit up but the function
\n" ); document.write( "will still be increasing on (-infinity,0]
\n" ); document.write( "--------------------------------------------------------
\n" ); document.write( "-f(x)-1 is a reflection in the x-axis followed by a vertical shift down one
\n" ); document.write( "If f(x) is decreasing to the right of the y-axis
\n" ); document.write( "-f(x) will be increasing to the right of the y-axis.
\n" ); document.write( "The -1 will move all points 1 unit down but the function
\n" ); document.write( "will still be increasing on [0,+infinity)
