In Problems 5 - 6, f"(x) is known. Find f(x) through anti-decrementation twice. Note that in this case your answer must involve two arbitrary constants; one of each anti-decrement. For example, if f"(x) = x, then f'(x) = x²/2 + C1, and f(x) =x³/6 + C1x + C2x,. Constants C1 and C2 cannot be combined.  Problems : 5) f''(x) = x^(4/3) 6) f"(x) = 2 (x+1)^(1/3)
