how do you graph
\n" ); document.write( "f(x) = {x + 2 if x < -2
\n" ); document.write( "or
\n" ); document.write( "f(x)=2x - 1 if x >= - 2
\n" ); document.write( "------------
\n" ); document.write( "Draw the coordinate system with x and y axis.
\n" ); document.write( "---------------
\n" ); document.write( "Mark an appropriate point as x=-2
\n" ); document.write( "-----------------
\n" ); document.write( "Graph the part of the line y=x+2 that is to
\n" ); document.write( "the left of x=-2.
\n" ); document.write( "To do that find two points that are to the left
\n" ); document.write( "like (-5,_3) and (-3,-1).Draw a line thru those
\n" ); document.write( "two points stopping when you get to x=-2.
\n" ); document.write( "----------------
\n" ); document.write( "Graph the part of the line y=2x-1 at and to the
\n" ); document.write( "right of x=-2. Find two points such (-2,-5)
\n" ); document.write( "and (0,-1). Draw a line thru them that goes no
\n" ); document.write( "further left than x=-2.
\n" ); document.write( "-----------------------
\n" ); document.write( "That is the piecewise graph you need.
