GCSE Secondary Maths Age 13-17 - Graphs: Graph Transformation 2 - Explained

The video tutorial explains graph transformations, focusing on the sine function. It covers the rules for transformations, emphasizing changes outside the function affecting the Y-axis and changes inside affecting the X-axis. The tutorial demonstrates translating the sine graph downwards by 2 units and provides tips for plotting and practicing these transformations. The importance of understanding these concepts for exams is highlighted.

What is the range of X values for the graph of Y = sin X discussed in the video?

• -360 to 360

• 0 to 360

• -180 to 180

• -90 to 90

If a change is outside the function, which coordinate does it affect?

• Both X and Y coordinates

• Y coordinate

• X coordinate

• Neither X nor Y coordinates

How does the graph of Y = sin X - 2 differ from Y = sin X?

• It shifts 2 units to the right

• It shifts 2 units upwards

• It shifts 2 units downwards

• It remains unchanged

What is the effect of a transformation inside the function on the graph?

• It has no effect

• It affects both coordinates

• It affects the X coordinate

• It affects the Y coordinate

What is the correct approach if a transformation involves adding a value inside the function?

• Subtract the value from the Y coordinate

• Add the value to the X coordinate

• Subtract the value from the X coordinate

• Add the value to the Y coordinate
