Let CTO,1] 3.(12 pts) Let f=f(x)-mx-1 and g = g have the inner product (x)-4x + m be two functions in q0,1]. Find the exact value(s) of m for which f and g are orthogonal.
do 11.3 please Example 11.2b Let us reconsider Example 11.2a, where we have 5 to invest among three projects whose return functions are f(x) = 2x . 1+x f(x) = 10( I-e-x). Let xi (j) denote the optimal amount to invest in project 1 when we have maxlfi(l), f2(1), f3(1))-max(5, 1632 6.32, a total of j to invest. Because we see that Xi(1)=0, X2(I) = 0, x3(1)=1. Since max(f(xdl) + I)-f(xdl)) = max(5, I, 8.65-6.32) = 5. we have X1(2)...
