Why does 𝘅 − 𝟮 move a graph to the 𝗥𝗜𝗚𝗛𝗧?
It feels backwards at first.
That’s because there are two different kinds of graph transformations:
• Changes 𝗼𝘂𝘁𝘀𝗶𝗱𝗲 the function affect the 𝗼𝘂𝘁𝗽𝘂𝘁
• Changes 𝗶𝗻𝘀𝗶𝗱𝗲 the function affect the 𝗶𝗻𝗽𝘂𝘁
In this video, we build the intuition visually using graphs instead of memorizing rules.
𝗬𝗼𝘂’𝗹𝗹 𝘂𝗻𝗱𝗲𝗿𝘀𝘁𝗮𝗻𝗱:
✓ Why 𝗳(𝘅) + 𝗮 shifts a graph up
✓ Why 𝗳(𝘅) − 𝗮 shifts a graph down
✓ Why 𝗳(𝘅 + 𝗮) shifts a graph left
✓ Why 𝗳(𝘅 − 𝗮) shifts a graph right
✓ Why the “inside” sign seems flipped
✓ How input changes differ from output changes
✓ How to read transformations directly from equations
✓ How the rule extends to forms like 𝘆 = (𝘅 − 𝗵)² + 𝗸
𝗧𝗵𝗲 𝗸𝗲𝘆 𝗶𝗱𝗲𝗮:
𝗢𝘂𝘁𝘀𝗶𝗱𝗲 𝘁𝗵𝗲 𝗳𝘂𝗻𝗰𝘁𝗶𝗼𝗻 → 𝗼𝘂𝘁𝗽𝘂𝘁 𝘀𝗵𝗶𝗳𝘁
𝗜𝗻𝘀𝗶𝗱𝗲 𝘁𝗵𝗲 𝗳𝘂𝗻𝗰𝘁𝗶𝗼𝗻 → 𝗶𝗻𝗽𝘂𝘁 𝘀𝗵𝗶𝗳𝘁
And for inside shifts:
𝗳(𝘅 − 𝗮) → 𝗿𝗶𝗴𝗵𝘁 𝗯𝘆 𝗮
𝗳(𝘅 + 𝗮) → 𝗹𝗲𝗳𝘁 𝗯𝘆 𝗮
Once you understand why this happens, graph transformations stop feeling like a sign trick you have to memorize.
