Question

the bottom the range has the same numbers so I just need the domain and range help plz!!

Answer 1

How to identify domain and range from co-ordinate pairs?

• If a pair be (x,y)

Domain=x

Range=y

Hence.

In the graph here

$\\ \sf\longmapsto D_f=0\leqslant x\leqslant y$

$\\ \sf\longmapsto R_f=0\leqslant y\leqslant 14$
