Diketahui fungsi f(x)=ax+b Jika f(0)=-4 dan f(-3)=-22 Tentukan f(2) Tolong dijawabb yaa

f(x) = ax+b
f(0) = b = -4
f(-3) = -3a+b = -22
           -3a-4 = -22
              -3a = -18
                 a = 6
f(2) = 2a+b
      = 2(6) + -4
      = 12 - 4
      = 8

Diketahui :

f(x) = ax + b
f(0) = - 4
f(-3) = - 22

Ditanya :
f(2) = ... ?

Jawab :
0a + b = - 4
- 3a + b = - 22
——————— -
3a = 18
a = 18/3
a = 6. ✩

- 3a + b = - 22
- 3(6) + b = - 22
- 18 + b = - 22
b = - 22 + 18
b = - 4. ✩

f(2) = 6(2) - 4
f(2) = 12 - 4
f(2) = 8.
