Question

Tolong ya yang no 8 sekalian cara nya

Answer 1

Fx = ax + b

f(0)
= a(0) + b = -2
= 0 + b = -2
b = -2

f(1)
= a(1) - 2 = 0
= a - 2 = 0
a = 2

f(x)
2x - 2

[B]

Answer 2

F(x) = ax + b , dgn
f(0) = -2 , dan f(1) = 0. Jadi,
f(0) = ax + b
= a.(0) + b = -2
= b = -2
f(1) = ax + b = 0
= a(1) + (-2) = 0
= a = 2
Maka rumus fungsi f(x) ny,
f(x) = 2x - 2 (b)
