What point would A' be after a dilation with a scale factor of 2 centered at (-7,-2)?

(-14,-4)

Step-by-step explanation:

Given the pre-image A=(-7,-2)

If A is dilated with a scale factor of 2

Then the image of A,

A' = (-7,-2) X 2

We multiply each coordinate point by 2

=(-7*2,-2*2)=(-14,-4)

Therefore, the point A' would be: (-14,-4)

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.
