Answer:
The net perfect number would be 28
Step-by-step explanation:
When you add up all the factors of 28 (other than 28) you get 28.
1 + 2 + 4 + 7 + 14 = 28
F(x)=-x+5
So
f(-4)= -(-4)+5
f(-4)= 4+5
f(-4)= 8
Only we have to substitute value of x then after simplification we will get answer..Hope this will help
