The correct answer is a. 3x + 6
In order to find a compound function, you must use the first letter in the function (in this case f) and plug the second letter (g) in where you see x's.
f(x) = x + 2
f(g(x)) = (g(x)) + 2
f(g(x)) = (3x + 4) + 2
f(g(x)) = 3x + 6
Answer:

Step-by-step explanation:

Graphing:
Slope intercept form y=mx+b
a is y, p is x
y=-2x+14
y=-x+9
Intercept at (5,4)
Answer:
Step-by-step explanation:
(D+R) = 80:2 = 40
D = 40-R
(D+8) * R = 72X
Thay D=40-R
(40-R+8)*R = 72X
R=1.55, D=38.45
