f(x) = -5x - 15
Let y = f(x)
y = -5x - 15
Switch the x and y places, and solve for y:
x = -5y - 15
-5y = x + 15
y = (x + 15)/-5
y = -(x/5) - 3
So the inverse of : f(x) = -5x - 15 is
-x/5 - 3

Answer: 296
Step-by-step explanation:
Unique addresses (population size) = 1,346
Sample size = 50
Number of children - - - - - - - No of household
0 - - - - 5
1 - - - - 11
2 - - - -13
3 - - - - 10
4 - - - - 9
5 - - - - 2
Number of households with more than 3 children :
That is, households with 4 and 5 children
Total = 9 + 2 = 11 households
Therefore, proportion of households with more than 3 children :
(11 / sample size) × population size
(11 /50) × 1346 = 296.12
Approximately 296 households
