![201617: functions, integrals. Let g be a function, defined in terms of some other
function f, such that
g(x) =
f(x)
f(x) + f(1 − x).
Suppose that f is non-zero on the interval (0, 1) and has known derivative f'.
a. Show that g(1 − x) = 1 – g(x). What is g(¹)?

c. Calculate g' in terms of f and f'. What is g'()?
d. Suppose that f'(0) = 0 = f(0), and f(1) ‡ 0. Calculate g'(0) and g'(1).
e. Suppose that f(x) = 0 for x ≤ 0.
