Question

I would love if someone can please help me on this algebra problem??

Answer 1

From this question, it means that

`\begin{gathered} y=\sin x\text{ was translated to} \\ y=4\sin x \end{gathered}`

To be sure the required translation, let us see a quick look at the graph of the function and it's image

`y=\sin x`

And

`y=4\sin x`

Now, we can see that the image is an enlarged form of the original function

Therefore this is a dilation. And since the increase in size is vertical, that is across the y-axis, It is a Vertical dilation.

Hence the correct answer is Vertical dilation.
