We want to use the comparison test to determine whether 1 (z + 2x) 2/5 is convergent. Choose the correct argument. The integral is divergent since 1 1 2 (2/5) x for all x 2 1 and O (z+ 2x) 2/5 1 (2/5) x de = co . The integral is convergent since 1 1 S for all x 2 1 and O ( + 2x) 2/5 (2/5) e2x (2/5) e2x de = (4/5) e2 5 00. The integral is convergent since 1 S for all x 2 1 and O ( + 2x) 2/5 2/5 1 2/5 2/5 - 1 500 . The integral is divergent since 1 1 2 1 O (z + 2x) 2/5 (e2ac ) 2/5 e (4/5)x for all x 2 1 and e (4/5) I = 00 . The integral is convergent since 1 S 1 O (z + 2x) 2/5 (2x ) 2/5 e (4/5)x for all x 2 1 and da 1 e (4/5) z (4/5) e4/5 50o . The integral is divergent since 1 1 2 for all x 2 1 and O (+ 2x) 2/5 2/5 1 2/5 dx = co
