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

$6$
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 $6$
