Another niche gem on the internet, thanks so much!

You’re an amazing teacher plz continue to do more videos on alevel math, your videos help me understand hard topics really well

You can reverse the order n first example if translation is by vector (0, 3)

For d - if I’d have done the translation first ( you never covered it in the video), it would be (0, -2) right ? Because when you multiply three by that one three, you’ll stick a three in front of the f(x) and three times ‘-2’ to get your minus 6?

for (d) i did translation (0, -2) then stretch in y direction by SF 3, does that get the same answer or is it only the X that is affected by the stretch?

[selenag]

Hey Sir, Is there a generic rule for the order of transformations? What I seem to to understand is that if it doesn't affect the same axis then order doesn't matter, however if the transformations affect the y-axis then the order is usually stretch then translate, however when it only affects the x-axis then it's translation then stretch...is that right?

[mhhm]

In c, wouldn't the translation be by vector (0, 4) in the first alternative too?

[jessicahall]

why is the translation in the y axis (part b) effected by the reflection in the x axis?

[WaqasK-Khan]

On the 2nd example, how come when doing a stretch of sf 1/3 in the y-direction you put 3y first? Is that just the way you've been taught it? Because multiplying by 1/3 straight away gets you the same answer. Thanks

[seongyunhong]

if the function is aF(bX+c)+d
could you tell me the order of transformation with the letters? Like for example (c --> b --> a --> d)

[umar]

why do you replace y with 3y at 3:15, I usually just straight away multiply the x side by 1/3, is this bad ?
