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. Connect the points and you have this line.
\n" ); document.write( "\"graph%28300%2C200%2C-10%2C10%2C-10%2C10%2C-3x-2%29\"
\n" ); document.write( "Happy Calculating, Sher!!!
