Answer:
D. 
and 
Step-by-step explanation:
The vertex of a function is controlled by the translations of the x and y value. Moving a vertex up and down is connected to the vertical position or the y-value. The y-value is the value that is added to the variable and is not squared.
Vertex form of a function is 
. In this case, k controls the vertical position of the vertex. If k is negative then the vertex will be moved down. So, if you want to move a vertex down by 5 units, then the k value must be -5.
Plug this into the formula to get the equation for k(x). This means that k(x) must equal 
.
Answer:
they are the same
Step-by-step explanation:
Answer:
The domain is the possible values of x that can be plugged into the function safely.
Step-by-step
Let D = domain of f
D = ALL REAL NUMBERS
1000*(1.06)^8. I'm lazy and don't want to type this into a calculator, but what you get out is the answer.
