Question

What conclusion can be made?​

Answer 1

I believe it’s the second one I’m not 10% sure tho

Answer 2

Answer: B) The value of k must be between 1 and 2

The function f(x) has a restricted domain [1, 2] which means
`1 \le x \le 2`

So we can only pick inputs in that interval. If x = k, then
`1 \le k \le 2`
