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