jika f(x) = 3x3-21x2-10x+3 tentukan hasil dari f'(2)
-55
-57
58
-58
Answer explanation
f(x)= 3x3-21x2-10x+3
f'(x)= (3 X 3x3-1) - (2 X 21x2-1) - (1 X 10x1-1)
f'(x) = 9x2-42x-10
f'(2) = 9(22) - 42(2)-10
f'(2) = 36-84-10
f'(2)= -58

diketahui duatu fungsi f(x) = 2x3-5x+1, maka f'(1)
-1
2
1
3
Answer explanation
f(x)= 2x3-5x+1
f'(x)= (3 X 2x3-1) - (1 X 5x1-1) + 0
f'(x) = 6x2-5
f'(1) = 6(12)-5
f'(1) = 6-5
f'(1)= 1

dari fungsi f(x) = (7x2-9x-8)2 tentukan f'(1)
100
-100
10
-10
Answer explanation
f(x) = (7x2-9x-8)2
f'(x) = 2(7x2-9x-8) (14x-9)
f'(1) = 2(7(12)-9(1)-8) (14(1)-9)
f'(1) = 2(7-9-8) (14-9)
f'(1) = 2(-10) (5)
f'(1) = -20 x 5
f'(1) = -100

dari fungsi f(x) = (7x2-9x-8)2 tentukan nilai dari f'(-1)
368
386
-386
-368
Answer explanation
f(x) = (7x2-9x-8)2
f'(x) = 2(7x2-9x-8) (14x-9)
f'(-1) = 2(7(-12)-9(-1)-8) (14(-1)-9)
f'(-1) = 2(7+9-8) (-14-9)
f'(-1) = 2(8) (-23)
f'(-1) = 16 x (-23)
f'(-1) = -368
