N = T(x n), then y n!T(x) by the continuity of T, and f(x n) = d(y n;x n) !d(T(x);x) = f(x) by the continuity of d Since f X!R is a continuous function on a compact set, it attains its minimum value at some a2X If T(a) 6=a, then f(T(a)) = d(T(T(a));T(a)). N = (x n;t n) and z = (x;t), we have x n!x, t n!t, and t n f(x n) Taking the limit of this inequality at n!1, we get that t liminf f(x n), and then the lower semicontinuity of fimplies that t f(x) Hence, z2epif, and epifis closed Remark Semicontinuous functions play an important role in variational. In the same way, in textbooks and when writing things out, we use different function names like f (x), g(x), h(x), s(t), etc, to keep track of, and work with, more than one formula in any single contextWith function notation, we can now use more than one function at a time without confusing ourselves or mixing up the formulas, leaving ourselves wondering "Okay, which ' y ' is this one?".

Example 2 f(x) = x n where n = 1, 2, 3 d In this example we answer the question “What is x n ?” Once we know the dx answer we can use it to, for example, find the derivative of f(x) = x4 by replacing n by 4 At this point in our studies, we only know one tool for finding derivatives – the difference quotient.
