Hi Sher, \n" ); document.write( " I need to graph \n" ); document.write( " \n" ); document.write( " f(x) = -3x-2\r \n" ); document.write( "\n" ); document.write( " Notice that this is a linear function. It is graphed the same way you would graph: y=-3x-2. f(x) and y mean the same thing, it's just a different notation. \n" ); document.write( ": \n" ); document.write( "Let x=0 \n" ); document.write( "f(0)=-3(0)-2 \n" ); document.write( "f(0)=0-2 \n" ); document.write( "f(0)=-2 Plot (0,-2) \n" ); document.write( ": \n" ); document.write( "Let x=2 (you can pick anything for x by the way, why don't you pick a couple of other numbers, and you'l find that they fall on the line as well) \n" ); document.write( "f(2)=-3(2)-2 \n" ); document.write( "f(2)=-6-2 \n" ); document.write( "f(2)=-8 Plot (2,-8) \n" ); document.write( "With linear functions, you only need two points to make a graph unless otherwise specified.
