Graph Transformations – Rap

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

If you’re gonna draw a graph you betta sharpen ya pencil
