for part 2a) you can take the antiderivative of f(x) from 1 to 4

2b)
f(x)=6x-e$$^{1-2x}$$
f'(x)=6-e$$^{1-2x}$$(-2)
f'(x)=6+2e$$^{1-2x}$$

f''(x)=2e$$^{1-2x}$$(-2)
f''(x)=-4e$$^{1-2x}$$

f''(x)+2f'(x)=0
-4e$$^{1-2x}$$+2[6+2e$$^{1-2x}$$]-12=0
-4e$$^{1-2x}$$+12+4e$$^{1-2x}$$-12=0
0=0
OWNED!

If these are HW questions, then no- you have to show an attempt at the problems first.
