Answer:
   3. vertical stretch by a factor of 2; shift right 1 and down 1
   4. shift left 4 and up 4 (no stretch or shrink)
Step-by-step explanation:
The vertex form equation is ...
   y = a(x -h)^2 +k
It represents a vertical stretch of the parent function by a factor of 'a', a right shift of 'h', and an upward shift of 'k'.
Compare the the given equations to the above form to see the transformations.

3. (a, h, k) = (2, 1, -1)   ⇒   vertical stretch by a factor of 2; shift right 1, down 1
4. (a, h, k) = (1, -4, 4)   ⇒   no vertical stretch; shift left 4, up 4
