The x-intercept is when thus,

thus,

Find derivative, (product rule)2 Find the co-ords of the turning point(s) of the curve

Set thus,

thus,

Now,

Thus, the turning points are on,

You should be able to do that now.3 Use the info above to draw a graph

This curve is the same as the other curve in the sense that it is shifted4 Use the graph to determine the co-ords of the turning points of the curve of

upby 10 units.
