Question

Reflecting y = – 3 sin x across the x-axis results in a function with equationQuestion 7 options:A) y = 3 sin x.B) y = – 3 sin (x + π).C) y = – 3 sin (x – π).D) y = – sin x.

Answer 1

We are to reflect

`y=-3\sin x`

Acreoss the x axis

To do this we will simply take the negative of y

That is the reflextion is

`-y=-3\sin x`

This can be simplified to be

`y=3\sin x`

Therefore the answer is y = 3 sin x
