4. (a) (10 marks) Let f be integrable on [a, b]. Suppose c ER and g: (a + c,b+c] → R such that g(x) = f(x-c), rela+b+c Prove that g is integrable on [a+c,b+c] and b+c [ f(x) dx - 9(2) de dz= Jate (b) (20 marks) Let h: RR be integrable on every bounded interval and h(x + y)=h(z) +h(y) for any r, yER Show that h(z)= er for any z ER, where c= =h(1). (Hint: Fix any z, y ER and integrate h(t+y)=h(t) +h(y) with respect to t on [(0,r). Then use
