f(x) -4 shifts it down 4 units from f(x)
when we add or subtract from f(x) this causes a shift in the vertical direction.
when we add it shifts it up.
when we subtract is shifts it down
f(x) -4 shifts it down 4 units

over 5 days, the pool loses 11 inches of water.
since the leaky pool is losing water at a rate of 2 inches of water each day, than we can find the amount of water the pool has lost over 5 days, by either adding 2 five times, or just multiplying 2 by 5:
so, the total amount of water lost over 5 days is 11 inches.
