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

The video tutorial covers graphing the function Y = sine X and its transformations. It explains the rules for transformations, focusing on changes outside and inside the function, and how they affect the Y and X coordinates, respectively. The tutorial demonstrates translating the graph of Y = sine X downwards by 2 units, providing step-by-step instructions and emphasizing the importance of plotting key points accurately. It concludes with a discussion on the marking criteria for graph transformations.

What is the range of X values for the graph of Y equals sine X discussed in the video?

• -90 to 90

• 0 to 360

• -360 to 360

• -180 to 180

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 equals sine X change when a minus 2 is applied outside the function?

• It shifts 2 units upwards

• It shifts 2 units to the left

• It shifts 2 units downwards

• It shifts 2 units to the right

What is the purpose of using tracing paper when plotting the transformed graph?

• To measure angles precisely

• To erase mistakes easily

• To trace and accurately shift the curve

• To add color to the graph

How many points must be plotted correctly to earn one mark in the graph transformation question?

• 4 points

• 5 points

• 2 points

• 3 points
