hei kamu yg pintar pliss bntu jawab ya hehe..
Jawaban:
Penjelasan dengan langkah-langkah :
f(x) = 3x + 2
f(2) = 3(2) + 2
f(2) = 6 + 2
f(2) = 8
nilai a = 8
f(b) = 3b + 2
8 = 3b + 2
6 = 3b
b = 2
nilai b = 2
= a + b
= 8 + 2
= 10
Jawaban:
10
Penjelasan dengan langkah-langkah:
diketahui
Fx= 3x +2
f(2)= a
f(b) = 8
ditanyakan
nilai a+ b
jawab;
f(x) = 3x+2
•f(2)= 3(2)+ 2 =8 => a=8
•f(b) = 3x +2 = 8
=> 3x =8-2
=> x = 6/3 = 2 => b=2
a + b = 8 + 2 = 10
