Question

What is the output on this graph when the input is 2?

Answer 1

Every pair have ( x , y ) which means x is input and y is output .

Here , input is 2 (x)

then , let output be y ( indicate with 0 )

So , the co- ordinates are ( x , y ) = ( 2 , 0 ) .

Answer 2

How to find input and output from the co-ordinates on the graph?

• If a pair be (x,y) then x is the input and y is the output

Here the co-ordinate having x=2 is

• (2,0)

So the output is 0
