2 answers:
Answer: Each friend get 3.5 cookies.
Step-by-step explanation: Given that two friends share 7 cookie equally.
We are to find the number of cookies that each friend get.
We will be using the UNITARY method to solve the given problem.
Number of cookies shared by 2 friends equally = 7.
Therefore, number of cookies that one friend get will be
Thus, each friend get 3.5 cookies.

Given:
The parent absolute function is
To find:
The new function if the parent function is translated up by 5 units and vertically stretched by a factor of 3.
Solution:
The translation is defined as
.... (1)
Where, k is stretch factor, a is horizontal shift and b is vertical shift.
If 0<k<1, then the graph compressed vertically by factor k and if k>1, then the graph stretch vertically by factor k.
If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.
If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.
Parent function is translated up by 5 units. So, b=5
It is vertically stretched by a factor of 3. So, k=3.
There is no horizontal shift. So, a=0.
Now, putting k=3, a=0 and b=5 in (1), we get
Therefore, the correct option is D.
