Answer:
A.
Step-by-step explanation:
In the picture, the estimated slope goes down, so it has to be negative, eliminating 2, B and D
It isn't a gradual line, as 6x is, so that is eliminated.
When we look at the estimated line, we can count out on the grid 3 to the right and 4 down, doing that a few times. If you then connect the dots, it will be a line probably very close to your estimate.
Answer:
Step-by-step explanation:
The base case in the recursive function are:
The recursive case is equal to:
So replace for :
In the new expression is a base case so you don't have to worry for that part, but is still the recursive case so evaluate again in
and are define as base cases so you replace for it's numbers:
Now return to and replace for the new values:
So the final answer is 20
