Evaluate f (1) = 3x + 8

11

Step-by-step explanation:

f (1) = 3 (1) + 8 = 3 + 8 = 11

Answer: 11

Step-by-step explanation: Here we're given the function f (x) = 3x + 8 and we're asked to find f (1). In other words, if we put an x into our function, we get a 3x + 8 out so what happens when we put a 1 into the function?

Well if we put a 1 into the function, that's f (1), we get a 3 (1) + 8 out.

Now all we have to do is simplify on the right side.

3 (1) is 3 so we have 3 + 8 which is 11.

So f (1) is 11.
