Question 3 Which of the following is a power series representation for the function 1 1+ 2-2 - ? O -- 2n 7 0 72 0 O DO 72 0 O (-1) 72 2 Question 4 Why is > (2ac + 3) 2" NOT a power series representation for the function 2x + 3 - ? 7=0 1-x O Because it doesn't converge for all x Because it's undefined when x = -3/2 O Because it's not a power series O Because it doesn't match the function
