Fun Fact: Did you know that René Descartes, the French mathematician who invented the Cartesian coordinate system (the x and y axes we use for graphing), was inspired by watching a fly buzz around his room? He realized he could describe the fly's position using three numbers!
This is where many students stumble. Let's say you have a function f(x).
Example: Consider the graph of y = x2. The graph of y = (x - 2)2 shifts the original graph 2 units to the *right*. The graph of y = x2 + 3 shifts the original graph 3 units *upwards*.
Reflections flip the graph across an axis.
Example: If you have the graph of y = sin(x), the graph of y = -sin(x) is a mirror image of the original graph across the x-axis.
These transformations change the scale of the graph.
Example: The graph of y = 2x2 is a vertical stretch of the graph of y = x2. The graph of y = sin(2x) is a horizontal compression of the graph of y = sin(x).
Interesting Fact: Graph transformations are used extensively in computer graphics and animation. By applying transformations to mathematical functions, animators can create realistic movements and effects.
By understanding these common pitfalls and practicing diligently, your child can master graph transformations and excel in their E-math exams. Jiayou!
