### Integration Sub Topics

Alternative Form, **Area between a Graph and the X-axis**, Area between 2 Graphs, Area using Rectangles, Average Vale, Find f(x) from f'(x), find an Antiderivative, find Expression from Graph, find Value of Expression, find the Point of Intersections, find Pronumerals.

The video below is from the **Area between a Graph and the X-axis** sub topic. It has my solution to Question 3 from the 2014 VCAA Maths Methods Multi Choice exam. This type of question relies on an understanding of the total area between a graph and the x-axis – 60% of students answered this question correctly.
