Verified answer
H(2) + h(-5) = 12a + b -5a + b = 1
-3a + 2b = 1
h(3) = -4
3a + b = -4
-3a + 2b = 1
3a + b = -4
___________ +
3b = -3
b = -1
3a + b = -4
3a - 1 = -4
3a = -3
a = -1
h(x) = -x - 1
f(×)=3a+b= 9
lalu-3a+b=-15
-6a+b= -24
a= -24
-24dibagi -6hasilnya4, makanilai a =4 terus3(4)+b=9
12+b=9
b=9-12
b=-3f(×)(2)adalah f(-2)=4(-2)-3=8
-3=-11
f (2)=4 (2) -3= 8-3=5 maka nilainya adalah-11+5=-6
