    Also in qs like of rate of reaction in which there is production on y axis and time on x and the values start from say 1,we should extend our curve to the origin,as er says that

    If it naturally seems to extend and follow in a straight line you should,in any other case,i guess you can extend it back

    Biology; Chemistry; Physics: Post your doubts here!

    Many candidates connected each set of points by three lines or, more commonly, by two straight lines joined by a small curve. In these cases one of the two marks allocated for the graphs was lost. The lines should also pass through the zero Thus the graph should pass through zero if it tends to...
