1) a) & b)

The x-intercepts are found by looking at the graph. The points on graph where the curve crosses the

x-axis are called the x-intercepts of the curve. From the graph, we can see that the curve crosses the

x-axis at points (-3,0) & (1,0).

The vertex of the curve is the point on the curve with lowest value of y-coordinate. We can see from

the graph ...
