Show that f:A-B and g:B-C are onto function then g°f:A-C is onto function?
Asked by hemanttkumarr | 31 May, 2018, 20:46: PM
Expert Answer
Since, f is onto. So, every element in f has an image in A. Similarlysince g is onto, so every element in c has an image in A.
So in g[f(x)] every image in C has an object in A.
Hence, g[f(x)] is onto.
