Draw the graph of y = sinx
Think about the RANGE.
Reflect in the line y = x
Think about the DOMAIN

This is a general knowledge question.

The immediate thing that comes to mind when it coves to inverses for graphs is that any graph is reflected using y=x i.e. turn y=sinx vertically, and then flip it across the y axis.

The domain of y=arcsinx should be -1 and 1, because these are the max and min range values of y=sinx
