I wrote this rap a couple of years ago for my top set year 11. They told me later that they were reciting it in the exam and they found it useful. The reference to Mr Minute Maths is because he has suggested that he would like to record it for me. I’ll post a link here when he does. Enjoy!
Graph Transformations.
It’s MC B squared in da house
And MrMinutemaths is gonna use his nouse
You got Linear, Quadratic, Trig and Exponential
If you’re gonna draw a graph you betta sharpen ya pencil
We’re rapping’ about graphs,
We’re doin’ the maths
And we can plot it on Autograph
f of x plus one
Is a translation
But you gotta know which direction
If it’s in the brackets
it affects the x
And does the opposite
of what you expect
If it’s on the outside then it’s on the y
And then you don’t even have to try
We’re rappin’ about graphs,
We’re doin’ the maths
And we can plot it on Autograph
2 f of x
Now that’s a stretch
Scale factor 2
in the y, not x
F of 2 x is also a stretch
Scale factor reciprocal on the x
We’re rappin’ about graphs,
We’re doin’ the maths
And we can plot it on Autograph
Minus f of x
You’re gonna reflect
y values negative
Reflect in x
f of minus x
is also reflect
x values negative
y-axis reflect
We’re rappin’ about graphs,
We’re doin’ the maths
And we can plot it on Autograph
It’s MC B squared in da house
And MrMinutemaths is gonna use his nouse
You got Linear, Quadratic, Trig and Exponential
If you’re gonna draw a graph you betta sharpen ya pencil
