MA 241 Test 4 Fall2007 Form B *Show all work clearlY. * Begin each problem on a new Pa!e. * NO CALCULATORS, NO CELL PHONES, NO PDAS. When proving convergence or divergence, name the test, show the criteria is met, and make a conctuding statement. - *(-1)'(-r+2)' 1. (20 points) Find the interval of convergence for >-=, The answer is not converges for all x or converges at one value ofx' 2 , ( I 0 points) Find a power series representation centered about 0 for the function f ( x\ = -f ^ . Do not state the radius or interval of convetgence due to time. 1+ 4x' 3. (15 points) a.
