Ja i3D1 3. A function is called increasing on an interval I if f(x) < f(y) for all in I. Suppose f is increasing on [a, b). Partition [a, b] into n equal pieces, each of width A = (b – a)/n. Find simple upper and lower bounds for Ja Ef(Ti)A. (Hint: In each [pi-1 – pi], f(pi-1) < f(x) < f(p;); also note that i=1 L(pi) – f(pi-1) = f(b) – f(a).) alsvmin ba i=1 taoo) ai eil diod...
