Can you tell me if my answer would be marked correct? My answer was Transformation of 4,-3 (T 4,-3) followed by a reflection in the x-axis.If I graphed the question and wrote that, would I get full credit

 

 

 

 

Hi Abraham,

The question is

Graph and label the equations

a: y = x2
b: y = - (x - 4)2 + 3

Describe the composition of transforms performed on a to get b.

If by T 4,-3 you mean the linear transformation that takes (0,0) to (4,-3) then I agree with your answer.

I would have said

  1. A horizontal translation of 4 units, then
  2. a vertical translation of -3 units, and finally
  3. a reflection in the x-axis.
