Countdown to Exams - Day 73 - Translations and reflection of graphs

Today's focus in our countdown to exams is the topic of Translations and reflections of graphs. You will be given a function (graph) and be asked to manipulate the function and sketch a new graph sometimes labelling the key points on the graphs. Starting with translations, when you add to the function f(x)+a or f(x+a), this causes the graph to move up/down or left/right.

f(x)+a is a movement up/down by a units. f(x+a) is a movement left/right by a units (+=left, -=right).

Reflections are caused by making the function negative or the variable negative.

-f(x) is a reflection in the x axis (the outputs are reversed). f(-x) is a reflection in the y axis (the inputs are reversed)

Countdown to Exams - Day 60 - Transformations

Today we look at the popular topic of Transformations. There are four types of transformations to be aware of 1) Reflections (flipping a shape) 2) Rotations (turning a shape) 3) Translations (sliding a shape) and 4) Enlargements (altering the lengths of a shape). With each type of transformation, there are certain statements that need to be mentioned in order to secure full marks. A good indicator of how many things you need to state can be seen by the number of marks on offer.

A little tip: Ask for tracing paper with any transformation question so you can double check by tracing the shape and seeing if it matches up!
