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.
