Jawaban:
Penjelasan dengan langkah-langkah:
f(x)= ax²+bx+c
f(1)=a(1)²+b(1)+c
6 = a+b+c
f´(0)= 2ax+b
2 = 2a(0)+b
2 = 0+b
2 = b
f´(1)= 2ax+b
4 = 2a(1)+b
4 = 2a+b
4 = 2a+2
4-2 = 2a
2 = 2a
a = 2/2
a = 1
a+b+c=6
1+2+c=6
3+c=6
c=6-3
c=3
2a+b+3c=
2(1)+(2)+3(3)=
2+2+9 =
4+9 =
13 [✓]

Suatu fungsi dirumuskan dengan
f(x) = ax² + bx + c. Jika
f(1) = 6, f'(0) = 2, dan f'(1) = 4,
nilai 2a + b + 3c adalah berapa?
13 ✔️
Kenapa 13?
-----------------------------------------------
f(x) = ax² + bx + c
f(1) = 6
6 = (1)²a + 1b + c
a + b + c = 6
-------------------------
f'(0) = 2
f(x) = ax² + bx + c
f'(x) = 2ax + b
f'(0) = 2
2 = 2a(0) + b
b = 2
-------------------------
Dengan
f'(x) = 2ax + b
f'(1) = 4
4 = 2a(1) + b
4 = 2a + 2
2a = 4 - 2
2a = 2
a = 2/2
a = 1
-------------------------
a + b + c = 6
1 + 2 + c = 6
c = 6 - 1 - 2
c = 5 - 2
c = 3
-------------------------
nilai 2a + b + 3c =
2(1) + 2 + 3(3) =
2 + 2 + 9 =
13 ✔️
