The recipe uses

cups of white flower together with 6 cups of wheat flower.
Therefore, the combined quantity of flower equals

If

represents that combined amount, the equation to write is:

Constraints are as follows:
y can only be

6
Note that if y = 0 then x would have to be -6, which is not possible.
Here are 3 questions with their respective answers.1) Find
Answer: 4.Explanation:This expression indicates the
limit as the function f(x) approaches 2 from the right side.You should apply the function (the line) from the right side of 2 and get as close to x = 2 as you can.
That line has an open circle at
y = 4, which is the limit we are looking for.
2) Analyze the graph to see if the limit exists.Answer: 

To find each limit,
utilize the function approaching from the direction of x.It's important to note that since the two limits differ, it is concluded that the limit of the function as x approaches 2 does not exist.
3)
Answer: -1
To determine the limit as the function approaches 3 from the left,
follow the line ending with an open circle at (3, -1).Hence, the limit is -1.
