My school uses the Jacaranda textbook and I've done all the questions so far up to Chapter 6 (functions, transformations, logs/exp functions, differentiation) and my teacher said the first SAC would cover those chapters/topics. However, integration and anti-derivatives are covered in later chapters and thus not 'expected' for us students to know prior to the test. I don't remember the exact details on the SAC, but all the questions were related to a given tangent segment family or something like that and asking about a given function such as y=f(x)=x^n. There were about 4 points labelled on the graph for f(x)=x^n, I don't remember the exact labels. For example, O being the origin, T(a, a^n) being the endpoint of the curve, S being the x-intercept of the tangent at T (or when x=a) and S'(?, ?) being the coordinate of the y-intercept of such tangent. A lot of questions were related to a tangent segment functions or family or something, which we have never covered in class before and also finding the area under the curve without the use of integration. If anyone has knowledge on these type of questions and how to answer them or even the 2016 Application task from QATs that would be much appreciated. I have never seen these types of questions before in the textbook and even some practice SAC's I got from the forums around here. I was pretty confident going into the SAC since I've been aceing the quizzes we have to complete after each chapter of the textbook, but I was dumbfounded when I came across the actual SAC.
Sorry if I'm just being dumb and missing something obvious, thanks heaps :)
