Explanation & Answer
Hello,Here's the complete work. Check it out and reach out to me if you face any issue at all.
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 ...
