Question

To long dong kerjain, besok dikumpulin no????

Answer 1

DF(x)/dx=ax+b
F(x)=∫ax+b
=a/2x^2+bx+c

F(0)=c
F(0)=3+F(-1)
F(-1)=F(0)-3
=c-3

F(-1)=a/2-b+c
c-3=a/2-b+c
a/2-b=-3
a-2b=-6

F(1)=a/2+b+c

F(1)-F(0)=5
a/2+b+c-c=5
a/2+b=5
a+2b=10

a+2b=10
a-2b=-6
------------ +
2a=4
a=2
b=4

a+b=2+4=6
Jawabannya B
