<u>Answer:</u>
The marked price of the article is 22,600
<u>Explanation: </u>
Given, selling price of an article SP = Rs. 18080
To calculate marked price MP, the formula used is
Discount D = 20%
Substituting the given values
SP =
18080 =
MP = Rs. 22,600
Therefore the marked price of the article is 22,600
These are 3 questions and 3 answers.
1) Find
Answer: 4.
Explanation:
The expression means the limit as the function f(x) approaches 2 from the right.
Then, you have to use the function (the line) that comes from the right of 2 and gets as close as you want to x = 2.
That is the line that has the open circle around y = 4, and that is the limit searched.
2) Use the graph to determine the limit if it exists.
Answer:
To determine each limit you use the function from the side the value of x is being approached.
Note, that since the two limits are different it is said that the limit of the function as it approaches 2 does not exist.
3)
Answer: - 1
To find the limit when the function is approached to 3 from the left you follow the line that ends with the open circle at (3, -1).
Therefore, the limit is - 1.
