Pls lah, jwb coeg :((((((((
Penjelasan dengan langkah-langkah:
1. g (x) = 4x – 7
g(-2) = 4(-2) – 7 = -15
g(-1) = 4(-1) – 7 = -11
g(0) = 4(0) – 7 = -7
g(-1) = 4(1) – 7 = -3
g(2) = 4(2) – 7 = 1
g(3) = 4(3) – 7 = 5
2. g (x) = 6x + 5
g(a) = 6a + 5 = -19
6a = -19 – 5
6a = -24
a = -4
3. f (x) = ax + b
f (5) = 5a + b = 1
f (-4) = -4a + b = 10
4. f (x) = ax + b
a.) f(2) = 2a + b = 1
f(-6) = -6 a + b = -23
_________________ –
8a = 24
a = 3
2a + b = 1
2(3) + b = 1
6 + b = 1
b = -5
3 + (-5) = -2
b.) f(12) = 2(12) + (-5) = 19
c.) f(3) = 2(3) + (-5) + f(-4) = 2(-4) + (-5)
= 1 + (-13) = -12
