The formula a=46c gives the floor area a in square meters that can be wired using c circuits. if a room is 322 square meters, how many circuits are required to wire this room?

Given formula   a=46/c

Given number: a=322 square meters 

Problem asks: c=? Circuits required wiring in the room.
Solution:

   a=46/c
322=46/c 

322/46=7 
c=7

So, there are 7 circuits are required to be install in the room with in the 322 square meters.

i think is g(1)=-1.

hope that i can
