Answer 1

Hello Chalyce,

 

z and being being inverse functions tells us that (x,y) set for one comes out as (y,x) for the other.  This means that since it is given that z(-2)=6, it must be the case that p(6)=-2

 

However, we are given no information about the ordered pair for either function with the number 10.  If they said that z(1)=10, for example, then the answer would be p(10)=1.  We don't have enough information to determine the answer.
