For example,\[\rm 3x = 18 \implies x\mapsto6\]Will that be the correct notation?

Also check this one:\[\rm x^2 = 9\implies x\mapsto(3,3)\]

\[f:x \rightarrow3x\] is that cornened with functions

The first is OK because it defines x as a constant function.

oldrin.bataku Group TitleBest ResponseYou've already chosen the best response.1
The second defines x as a constant function yielding (3,3) which doesn't make much sense here... perhaps you mean: \[x=\pm3\text{ or }x\in\{3,3\}\]

mapped is in relation to functions.

Yes, okay, but how can you say that \(\rm x\) maps to 3 or 3?

@ParthKohli a map is a relation between sets; \[x\mapsto3\text{ is essentially the same as }F(x)=3\]

Yes, that's exactly what I am taught. Was just confirming. :)

Well, so how can say write this? x maps to either 3 or 3.

ParthKohli Group TitleBest ResponseYou've already chosen the best response.0
Yes, yes, I know that. :P

As I said, I need to use the mapping symbol for showing the solution of an equation.
 2 years ago

ParthKohli Group TitleBest ResponseYou've already chosen the best response.0
My current question is, how can we use the mapping symbol to show two solutions of an equation?
 2 years ago

oldrin.bataku Group TitleBest ResponseYou've already chosen the best response.1
That makes virtually no sense. Do you know what the symbol means?
 2 years ago

estudier Group TitleBest ResponseYou've already chosen the best response.1
That is not usual...
 2 years ago

ParthKohli Group TitleBest ResponseYou've already chosen the best response.0
Yes, I know what mapping means... ugh. Can we even use the mapping symbol to show two solutions of an equation?

Not really...

If you knew what a map was you wouldn't ask a question like that; no, you can't because that's not what it's for. That's like asking "can I use a telescope to write?"

How would you represent that the solutions of equation \(\rm x^2 = 9\) are \(3\) and \(3\)?

Well, one way is just to write it like u just did...:)

x^2 = 9 > x = plus/minus 3

ParthKohli Group TitleBest ResponseYou've already chosen the best response.0
\[\rm x^2 = 9 \implies x=\pm 3\]right?
 2 years ago

estudier Group TitleBest ResponseYou've already chosen the best response.1
That's the same, yes...

Thank you both, I'm returning with another question. :P
