Answer:


(-4,32)

Explanation:

Given points are
(-1,-8)

And given transformation is
D_4
r_(x-axis)

We will start from left to right.

First transformation is reflection about x-axis.

When we reflect about x-axis
(x,y)\ became\ (x,-y)

So,
(-1,-8)=[-1,-(-8)]=(-1,8)

Now next transformation is dilation with a factor 4.

If we do dilation with a factor
'k' to the point
(x,y)

New co-ordinates after dilation became
(kx,ky)

So,
(-1,8)\ became\ (-4,32)
