Final answer:
The value of f(3) - 9(2) is found by calculating f(3) as 5 and 9(2) as 18, subsequently subtracting the two results gives -13. However, this result is not listed among the provided choices, indicating a possible error in the question or choices.
Step-by-step explanation:
The student is asking to find the value of f(3) - 9(2) given that f(x) = 3x – 4 and g(x) = x^2. First, we need to calculate f(3) by plugging x=3 into the function f(x). Secondly, we calculate 9(2) which is simply 9 multiplied by 2.
Let's start by calculating f(3):
f(3) = 3(3) – 4
f(3) = 9 – 4
f(3) = 5
Next, we calculate 9(2):
9(2) = 18
Now subtract 9(2) from f(3) to find the value:
f(3) - 9(2) = 5 - 18
f(3) - 9(2) = -13
The value of f(3) - 9(2) is -13, which is not listed among the provided choices. Therefore, it seems there might be an error in the provided choices or in the phrasing of the question.
