Answer:
The answer to your question is: f(g(1)) = 
Step-by-step explanation:
Data
f(x) = 
g(x) = 5x - 7
find: (fog)(1)
f(g(x)) = 
f(g(x)) = 
f(g(1)) = 
f(g(1)) = 
Answer:
k = 1
Step-by-step explanation:
Given that,

If (x+1) is a factor of (x), we need to find the value of k.
Using remainder theorem to find it.
Put (x+1) = 0
x = -1
Put x = -1 in equation below.

So, the value of k is 1.
