Question

What is the amplitude for the function `y=6sinx`?

Answer 1

`6`

The `sin x` -function goes from `0` and `1` via `0` to `-1` and back again to `0`
So the maximum "distance" from `0` is `1` on either side.

We call that the amplitude, with in case of `sin x` equals `1`

If you multiply the whole thing by `6`
then the amplitude will also be `6`
