Provide an appropriate response.Find the absolute maximum and minimum values of f(x) = 2x - ex on [0, 1].
A. Maximum = ln 4 - 2 at x = ln 2, minimum = 1 at x = 0
B. Maximum = 0 at x = ln 2, minimum = 1 at x = 0
C. Maximum = ln 4 - 2 at x = ln 2, minimum = -1 at x = 0
D. Maximum = ln 2 - 2 at x = ln 2, minimum = -1 at x = 0
