5. (This question shows an alternative definition for the term differentiable, one that is useful when you study advanced calculus (in R" instead of R).) Let f: R+R and a ER. Prove that f is differentiable at a if and only if there exists a function L:RR which is continuous at a and satisfies f(x) - f(a) = L(x)(x - a) for all x ER Suggestion: If f is differentiable at a, try to define the L function separately at...

Theorem 10.1.15 (Chain rule). Let X, Y be subsets of R, let xo e X be a limit point of X, and let yo e Y be a limit point of Y. Let f : X+Y be a function such that f(xo) = yo, and such that f is differentiable at Xo. Suppose that g:Y + R is a function which is differentiable at yo. Then the function gof:X + R is differentiable at xo, and .. (gºf)'(xo) = g'(yo)...
