Answer:
Solution below.
Step-by-step explanation:
This question may seem complicated, but it is really on the concept of substitution.
So given:
f(x) = 3x
g(x) = x - 4
h(x) =
We are asked to find (h•(f-g))(2).
Note: This is not a composite function.
First, lets find (h•(f-g))(x) first.
(f-g)(x) = f(x) - g(x) = 3x - (x - 4) = 2x + 4
(h•(f-g))(x) =
Now we can find (h•(f-g))(2) by substituting x = 2 into the function.
(h•(f-g))(2) =
Find A ∩ B if A = {2, 5, 8, 11, 14} and B = {1, 3, 5, 7}. {5} {1, 2, 3, 5, 7, 8, 11, 14}

Answer:
A ∩ B = {5}
Step-by-step explanation:
We are trying to find the intersection (what they both have in common)
A = {2, 5, 8, 11, 14}
B = {1, 3, 5, 7}
The only thing they both have in common is 5
A ∩ B = {5}
