I think that people here is sometimes too keen on closing question deeming them “problem statement questions”.
Here's today example: indications equation $a^x=x+2$
Check the original question, which I report the entire code of
a^x=x+2 has two real solutions.I need to find a values.
A) (1, infinity)
C) (1/e , e)
D) (1/(e^e), e^e)
E) (e^(1/e), infinity)
I tried to solve and I did it but I don't understand some things.
I let a picture below to see.
First, I need to know if there's other way to solve this kind of exercise.I would be happy if I would get some ideas.
Also, from my solution, I don't understand why from that table results just one solution and from the graphic results two solutions.Usually, to see the number of solutions I use this kind of table.
For a>1 f decrease from infinity to -1, then increase from -1 to infinity.I'm really confused.Need some indications here.
Thank you! [how I solved this exercise picture]
It's quite evident after clicking the link that a full (albeit wrong) solution is presented.
After receiving a (now deleted) comment from user The Great Duck, I just added a
! in front of the link (and reorganized the paragraph surrounding it for readability) and got accused of “trying to frame my opinion in a better light”.
I refuse this. The OP provided his/her attempt at a solution, I just made it visible to people who are too much in a hurry of closing without even bothering to check the link.
I got back to the question just to see that user The Great Duck had filed an edit suggestion consisting in removing the image and its link, when the image was there from the beginning. Everybody knows that very low rep users cannot directly add images. I possibly was hasty in not editing the question to add the
! when I answered and apologize to the OP.
