Answer 1

So..

All we have to do is think of something for (X) a simple replacement.

(THis took me a bit long to understand the Question)

Answer 2

Explanation:

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
