Number 1 is A, number 2 is B number three is D
Answer:
B
Step-by-step explanation:
The end behavior of a function is how the graph behaves as it approaches negative and positive infinity.
Let's take a look at each end.
As x approaches negative infinity:
As x approaches the left towards negative infinity, we can see that the graph is shooting straight upwards.
Therefore, as
, our function f(x) is increasing and increasing up towards positive infinity.
Therefore, the end behavior at the left will be:

As x approaches (positive) infinity:
As x approaches the right towards positive infinity, we can see the that graph is also shooting straight upwards.
Therefore, the end behavior will be exactly the same. As x approaches positive infinity, f(x) <em>also</em> approaches positive infinity.
Therefore, the end behavior at the right will be:

Therefore, our answer is B.
Answer:
cost for 21 months without considering cost of phone is $2,611.56
Total cost inclusive of cost of phone = $2,686.56
Step-by-step explanation:
cost of 2000 monthly anytime minutes plan = $ 124.36
So , in 1 month cost for given plan = $ 124.36
we have to find cost for 21 month
In 21 month, cost for given plan = 21 * cost of 1 month plan
In 21 month, cost for given plan = 21 * $ 124.36 = $2,611.56
cost for 21 months is $2,611.56.
Note, this cost is without considering the cost of phone as it is not mentioned cost of phone is to be included or not.
In case cost of phone is included then
Total cost inclusive of cost of phone = $2,611.56 + $75 = $2,686.56
