Recap of Unit 1

So basically, before we started any kind of lessons, we had a formal review on what we learnt in Form 4 and 5 add maths, FUNCTIONS. After all that, then our lessons started.


In Chapter, its basically just knowing polynomial functions and what they look like. Maybe like this :

and definitely not something like this :

In 1.1, we learned about power functions and the concept of power functions.
In 1.2, we studied the basic characteristics of polynomial functions in terms of domain and range mostly.
In 1.3,  it is the about shapes of graphs and equations. HARD to SKETCH, HARDER to use a GC. So many buttons to press just to get 1 graph.
In 1.4, it was transformations where we starting from the equation y=a f [k(x + b)] + c


In 1.5 and 1.6, the concepts touch gradient, which is related to the INSTANTANEOUS RATE OF CHANGE (IROC) & AVERAGE RATE OF CHANGE (AROC). **technically it means using differentiation at time to get the gradient of a tangent**
