यदि \(f:{1,2,3}\to{0,1,2,3}\), (f(x)=x-1), तो (f) का ग्राफ कौन सा है?
If \(f:{1,2,3}\to{0,1,2,3}\), (f(x)=x-1), what is the graph of (f)?
Explanation opens after your attempt
A. \({(1,0),(2,1),(3,2)}\)
Concept
For (x=1,2,3), (x-1) gives (0,1,2). In the graph, keep the order as ((x,f(x))).
Why this answer is correct
The correct answer is A. \({(1,0),(2,1),(3,2)}\). For (x=1,2,3), (x-1) gives (0,1,2). In the graph, keep the order as ((x,f(x))).
Exam Tip
(x=1,2,3) पर (x-1) क्रमशः (0,1,2) देता है। ग्राफ में क्रम ((x,f(x))) ही रखें।
