Let f be a function defined as f(x) = 2ˣ + log₂x over the interval [1, 2]. What conclusion can be made about the value of k such that f (p) = 4?
A. The value of p is 18.
B. The value of p must be between 1 and 2
C. No conclusion can be made about because 1 <2<4
D. No conclusion can be made about p because fx is not continuous over the interval.
