To answer this question for four marks, all you need to do is identify one problem caused by the global shift (for one mark) and then expand on the problems this can lead to (for a further three marks). In t...

Golden rays of joy radiate through time-honoured glass. Bells sing, calling to students and teachers alike. It is a cheerful Friday afternoon; an air of feverish delirium coats the school. Picturesque and we...

A function, y = f(x), with y on the vertical axis and x on the horizontal axis, can be transformed by 3 different ways: It can be stretched (or shrunk)If y = f(ax), the function is stretched by a scale facto...

Because we're told that x = 6, we can just rewrite the original equation but replace the x with a 6. So: y = 15 + 5(6 + 2) 6 + 2 = 8, so we can rewrite this again as: y = 15 + 5(8) 5(8) is just another way o...

With simultaneous equations like these, you first want to get to a point where you have one equation with only one variable. To do this, you must eliminate one of the variables. In this case, if you multiply...
