temen bantuin donk pake cara ya 4soal itu pake cara

FUngsi LInier

a) f : x--> 3x  -2
f(x) = 3x - 2

b) domain  x ={ 0,1,2,3}

c) range  dari
f(0) = 3(0) - 2 = - 2
f(3) = 3(3) - 2 = 7
range  -2 ≤ y ≤ 7

d) f(-3) = 3(-3) - 2 = - 11
f(10) = 3(10) - 2 = 28

e) f(x)= 43
3x - 2 = 43
3x = 43+2 = 45
x = 15

12.
f(x) = ax + b
f(1) = -7 --> a + b = - 7
f(-3) = 1 --> -3a + b = 1
kurangkan --> 4a = - 8
a = -2 --> b = -7 - a
b = -7 -(-2) --> b = - 5
f(x) = ax + b -->> f(x) = -2x - 5

13) f(-5) =-2(-5) - 5
f(-5) = 10-5 = 5

14. g(x) = ax + b
g(1) = - 2 --> a + b = - 2
g(2) = 1 --->2a + b = 1
kurangkan  -a = - 3
a = 3 --> b = -2 - a  --> b = -2 - 3
b = - 5
a + b =  3 + (-5)
a + b =  -2
