Answer:
The domain is all values but x=4 and x=2
Step-by-step explanation:
f(x) = (x+1) / ( x^2-6x+8)
Factor the function
f(x) = (x+1) / ( (x-4) ( x-2))
The domain of the function is all values of x except where the function does not exist
This is where the denominator goes to zero
(x-4) ( x-2) =0
Using the zero product property
x-4 =0 x-2 =0
x=4 x=2
The domain is all values but x=4 and x=2

The William's family used the sprinklers for 59 hours.
Because it used 25L per hour so 25/1 is 25 so then you multiply 1475 by 25 and you get 59
= used sprinklers for 59 hours.
The Taylor family used the sprinklers for 73.75 hours.
Because it used 20L per hour so 20/1 is 20 then you multiply 1475 by 20 and you get 73.75
= Used sprinklers for 73.75 hours.
