dik: f(x)= ax+ b f(1)=0 f(0)= -2 tolong dijawab dengan cara yg lengkap dan jelas

f(x) = ax + b

f(1) = 0 ----> x = 1
a + b = 0

f(0) = -2
b = -2

a + b = 0
a = -b
a = 2

f(x) = ax + b
f(x) = 2x - 2 ✓

jawab

f(x) = ax + b

f(1) = 0 --> a(1) + b = 0
a + b = 0 ....(i)

f(0)= - 2 --> a(0) + b = -2
b = -2..(ii)

a + b =0
a -  2= 0
a =  2

f(x)  = ax +b
f(x) = 2x - 2
