Explanation: To get a feel for this information, let's first pick a random value for x. Let's say x = 2 The given info tells us that f(x) = f(x + 1) for all values of x So, f(2) = f(2 + 1) In other words, f(2) = f(3)
Let's try a different value of x. How about x = 3 The given info tells us that f(x) = f(x + 1) for all values of x So, f(3) = f(3 + 1) In other words, f(3) = f(4)
And so on.
We can see that f(2) = f(3) = f(4) = f(5) and so on So, if f(4) = 17, we can be certain that f(8) = 17 as well.
