Question 1132717
.


I'd like to make couple of notices.



1.    The solution by @MathLover1 in this post is THE COPY-PASTE of my solution from my post 

      https://www.algebra.com/algebra/homework/Graphs/Graphs.faq.question.1132689.html


<pre>
    I have nothing against using my solutions - but ask to refer to it.

    Especially in the cases when you COPY and PASTE it.

2.  &nbsp;&nbsp;Using my solution here, @MathLover1 <U>confirms</U> that her solution in her previous post


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;https://www.algebra.com/algebra/homework/Graphs/Graphs.faq.question.1132689.html


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;is wrong.



3. &nbsp;&nbsp;And the last notice to the visitor who posted the problem.


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;My dear, &nbsp;if you can not identify the answer in my solution with the answer in your list,
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;it means that your level in Math is &nbsp;0 &nbsp;(zero, &nbsp;ZERO).


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In this case, &nbsp;I don't know what you are doing at this forum and for whom I am working here.
