Multiple Choice

Solve the initial-value problem.
ytt+3yt4y=0,y(0) =2,yt(0) =1y ^ { tt } + 3 y ^ { t } - 4 y = 0 , y ( 0 ) = 2 , y ^ { t } ( 0 ) = 1


A) y=ex+15e3xy = e ^ { x } + \frac { 1 } { 5 } e ^ { - 3 x }
B)
y=15e2x+95e2xy = \frac { 1 } { 5 } e ^ { 2 x } + \frac { 9 } { 5 } e ^ { - 2 x }
C)
y=95ex+15e4xy = \frac { 9 } { 5 } e ^ { x } + \frac { 1 } { 5 } e ^ { - 4 x }
D)
y=e2x+15e2xy = e ^ { 2 x } + \frac { 1 } { 5 } e ^ { - 2 x }
E) None of these
