# Let A = { 2 , 3 , 5 } and B = { x , y } . Let p 1 and p 2 be the projections of A × B onto the first and second coordinates. That is, for each pair ( a , b ) ∈ A × B , p 1 ( a , b ) = a and p 2 ( a , b ) = b . a. Find p 1 ( 2 , y ) and p 1 ( 5 , x ) . What is the range of p 1 ? b. Find p 2 ( 2 , y ) and p 2 ( 5 , x ) . What is the range of p 2 ?
