ANSWER

It is horizontally compressed by a factor of 2 and reflected over the y-axis.

Step-by-step explanation

The parent function given to us is


y = √(x)

The parent function has been transformed to obtain


y = √( - 2x)

This transformation is of the form:


y = √(kx)

If


|k| > 1

then,there is a horizontal compression by a factor of k.

Hence


y = √( - 2x)

is horizontally compressed by a factor of 2.

Since -2<0, it is a reflection in the y-axis.

The correct choice is the last option.
