Question

Suatu fungsi di tent dg rumus f(x)=ax+b jika f(3)=1 dan f(-2)=-9 nilai a dan b ber turut turut adalh....

Answer 1

Verified answer

F(x) = ax + b

f(3) = 3a + b
1 = 3a + b
b = 1 - 3a

f(-2) = -2a + b
-9 = -2a + b
b = 2a - 9

b = b
1 - 3a = 2a - 9
-5a = -10
a = 2 ✓

b = 1 - 3a
b = 1 - 3(2)
b = 1 - 6
b = -5 ✓

Jadi, a = 2 dan b = -5
