Question

HELP? I don’t know the answer

Answer 1

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.
