Difference b/w range and codomain.
Can someone for the love of god explain to me the difference between range and codomain?
As per all the videos I’ve seen, codomain is defined as “Set of all possible outputs of a function”
For example:
f(x) = x^2
Literally impossible to have any negative number as an output with this function. Yet in all those videos they said:
“The codomain for x^2 will be set of all real numbers”
Should it not be set of all positive real numbers union with 0?
And agar aisa hi hai phir toh difference hua hi nahi codomain aur range mein? (pls help)
