Question

What is f(3) for f(x)=3x+2​

Answer 1

f(3) = 11

Explanation:

To evaluate f(3), substitute x = 3 into f(x), that is

f(3) = 3(3) + 2 = 9 + 2 = 11

Answer 2

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.
