Question

Can someone please explain this to me??
Write an equation for the following transformation of y=x: a vertical stretch by a factor of 4

Answer 1

y = A ( Bx + C ) + D

A = vertical stretch

thus

if the "parent function" is \(\bf y = x\)
the "transformed function" is \(\bf y = \color{red}{4}x\)

Answer 2

transformed just means, the parent function, or a basic barebones function, with PADDED WITH EXTRA STUFF AROUND

Answer 3

I just don't understand :c

Answer 4

a parent function is just usually a barebone variable expression

Answer 5

What does that mean?... I'm sorry I'm really terrible at math, it's not my cup of tea. I do a lot better when people explain things step by step..
