Diketahui h:x 9x-c dan h(6)=34 tentukan nilai h(-1)+h(3)

h(x) = 9x-c
36= 9*6-c
36=54-c
c= 54-36
c= 18

h(-1) = 9*(-1) - 18
h(-1) = -9-18=-27

h(3)= 9*3-18
h(3)=27-18=9
h(-1)+h(3)= (-27)+9 = - 18

h(x) = 9x - c

h(6) = 9(6) - c
34 = 54 - c
c = 54 - 34 = 20

h(-1)= -9-20 =-29
h(3)=9(3)-20=27-20=7

h(-1)+h(3)= -29+7=-22
