D(-1,-1), E(-8,-4), F(-8,-8)
Answer: $26
Step-by-step explanation:
Let the number of $2 price increases be x.
This means that if the price is 10+2x, 42-2x shoes are sold.
So, the revenue is (10+2x)(42-2x).
To maximize profit, we must maximize revenue.

The maximum is at
, so the price should be 10+2(8)=$26.
Answer:
The correct end behavior are;
As x approaches positive infinity, y approaches positive infinity (D)
As x approaches negative infinity, y approaches positive infinity (B)
Step-by-step explanation:
Here, we want to get the end behavior of the graph
Kindly note that the upward arrow represents a movement toward infinity
Thus, we have it as follows;
As the value of x increases (towards the right); the value of y tends toward positive infinity
secondly: as the value of x decreases, tends toward the left, the value of y also tends toward positive infinity
