Answer 2

Plot the graph first. You then need to apply the area of a trapezium to this problem.

You will see if you split the area under the graph into 4, each with a height of one in the y direction, 4 trapeziums. By using a formula to add up each of the areas of those 4 trapeziums, you get an approximate area for the area under the graph.

I am not to sure if the question is asking for the area under the graph and above the x-axis or, the area under the whole graph.

That explains how to do it with a slightly different method. Remember to read the whole web page to understand it completely.
