use counters model to solve this problem.eva has 2 apples in her basket.She eats 1 apple and gives 1 to her friend.How many appl
es does Eva have now?
2 answers:
Answer:
She has no apple now.
Step-by-step explanation:
We have given,
The original number of apples contained by Eva = 2,
In the below model,
After eating 1 apple,
Remaining apple she has = 2 - 1 = 1
After giving 1 apple to her friend,
The final number apples she has now = 1 - 1 = 0
Therefore, she has no apple now.

Step-by-step explanation:
Take the first derivative
Set the derivative equal to 0.
or
For any number less than -1, the derivative function will have a Positve number thus a Positve slope for f(x).
For any number, between -1 and 1, the derivative slope will have a negative , thus a negative slope.
Since we are going to Positve to negative slope, we have a local max at x=-1
Plug in -1 for x into the original function
So the local max is 2 and occurs at x=-1,
For any number greater than 1, we have a Positve number for the derivative function we have a Positve slope.
Since we are going to decreasing to increasing, we have minimum at x=1,
Plug in 1 for x into original function
So the local min occurs at -2, at x=1
