Diketahui rum us fungsi f(x) =ax+ b. Jika f(-4) = 13 dan f(3) = -1, maka nilai f(-2) adalah .... ....

Langsung aja y

f(-4) = -4a + b = 13
f(3) = 3a + b = -1
_____________-
-7a = 14
a = -2

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

f(x) = ax + b
f(x) = -2x + 5

f(-2) = -2(-2) + 5
f(-2) = -4 + 5
f(-2) = 1

Semoga berguna +_+
