# graph core 3 watch

1. The diagram shows the graph of y = f(x). It is given that f(−3) = 0 and f(0) = 2. Sketch, on separate diagrams, the following graphs, indicating in each case the coordinates of the points where the graph crosses the axes:
(ii) y = −2f(x).
i understand that negative means reflection in the x axis but i'm not sure how to draw this though. i normally get graph questions wrong quite often, any tips on improving?
