Answer:
f(3) = 11
Step-by-step explanation:
To evaluate f(3), substitute x = 3 into f(x), that is
f(3) = 3(3) + 2 = 9 + 2 = 11
Answer: f(3) = 11
Step-by-step explanation: Notice that f is a function of x.
So we want to find f(3).
We find f(3) plugging 3 in for x,
everywhere that x appears in the function.
So we have 3(3) + 2 which is 9 + 2 or 11.
So f(3) = 11.
