Best ResponseYou've already chosen the best response.0For example,\[\rm 3x = 18 \implies x\mapsto6\]Will that be the correct notation?

Best ResponseYou've already chosen the best response.0Also check this one:\[\rm x^2 = 9\implies x\mapsto(3,3)\]

Best ResponseYou've already chosen the best response.1The first is OK because it defines x as a constant function.

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

Best ResponseYou've already chosen the best response.1mapped is in relation to functions.

ParthKohli

Best ResponseYou've already chosen the best response.0Yes, okay, but how can you say that \(\rm x\) maps to 3 or 3?

oldrin.bataku

Best ResponseYou've already chosen the best response.1@ParthKohli a map is a relation between sets; \[x\mapsto3\text{ is essentially the same as }F(x)=3\]

Best ResponseYou've already chosen the best response.0dw:1350632977047:dw f is a function that maps x to y

Best ResponseYou've already chosen the best response.0Yes, that's exactly what I am taught. Was just confirming. :)

ParthKohli

Best ResponseYou've already chosen the best response.0Well, so how can say write this? x maps to either 3 or 3.

ParthKohli

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

Best ResponseYou've already chosen the best response.1So where is your function?

Best ResponseYou've already chosen the best response.1\[x : \mathbb{R}\to{3,3} \]

ParthKohli

Best ResponseYou've already chosen the best response.0Here:\[\rm x^2  9 = 0\]

Best ResponseYou've already chosen the best response.1\[x\in\{3,3\}\text{ or }x=\pm3\]

Best ResponseYou've already chosen the best response.0As I said, I need to use the mapping symbol for showing the solution of an equation.

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

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

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

Jonask

Best ResponseYou've already chosen the best response.0\[x:y \rightarrow \pm \sqrt{9}\]

oldrin.bataku

Best ResponseYou've already chosen the best response.1If 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?"

ParthKohli

Best ResponseYou've already chosen the best response.0How would you represent that the solutions of equation \(\rm x^2 = 9\) are \(3\) and \(3\)?

oldrin.bataku
 2 years ago
Best ResponseYou've already chosen the best response.1\[x=\pm3\text{ or }x\in\{3,3\}\]

estudier

Best ResponseYou've already chosen the best response.1Well, one way is just to write it like u just did...:)

Best ResponseYou've already chosen the best response.0What will the full mathematical sentence be? @estudier @oldrin.bataku

estudier

Best ResponseYou've already chosen the best response.1x^2 = 9 > x = plus/minus 3

ParthKohli

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

estudier
 2 years ago
Best ResponseYou've already chosen the best response.1That's the same, yes...

Best ResponseYou've already chosen the best response.0Thank you both, I'm returning with another question. :P
