Final answer:
To find f(g(x)), substitute g(x) into the function f(x) and simplify. The answer is -3.
Step-by-step explanation:
To find f(g(x)), we need to substitute g(x) into the function f(x). From the given information, we have g(x) = \frac{1}{3} \times 7. Substituting this value into f(x) = 4 - 3x, we get:
f(g(x)) = 4 - 3(\frac{1}{3} \times 7)
Simplifying the expression:
f(g(x)) = 4 - 7
f(g(x)) = -3
Therefore, the correct answer is d) -3.
