Answer:
(f ○ g)(11) = - 1
Step-by-step explanation:
evaluate g(11) then substitute the result obtained into f(x)
g(11) = 11 - 7 = 4 , then
f(4) =
- 3 = 2 - 3 = - 1
First, you need to have j on it own. Since j is over 4-8, you times both sides of the inequality so the /4-8 is canceled.
Your new inequality equation is j<4(4-8). Solve the bracket and then times the answer by 4.
~ j<4(-4)
~ j<-16
