# Thread: reflection in axis

1. ## reflection in axis

Okay, new question.

Describe how the point (-3,5) would change if you reflected it across the x-axis and vertically stretched it by a scale factor of 3? I got (3,15) while my teacher got (3,-15)

I honestly think I'm right on this one.

2. ## Re: Given f(x) = -x^2 + 3x -6, find f(-3).

If you reflected it across the x-axis it would become (-3,-5) then the vertical stretch would give?
