Answer 1

Jawaban:

1. A

2.D

3.D

4.

5.D

6.B

Penjelasan dengan langkah-langkah:

1. f(x)=(2x+6) (3x-5)

=6x²-10x+18x-30

=6x²+8x-30(dibagi 2)

f'(x) = 12x+4

f'(-2) =12(-2) +4

=(-24) +4

=-20

2. f(x) =(x²-2x)³

f'(x) =3(x²-2x)²

3.f(x)=-7x^-6+5x³-9x+5

f'(x)= -6.(-7)x^-5 +3.5x²-9

=42x^-5+15x²-9

f'(1)=42(1)^-5+15(1)²-9

=-42+15-9

=-36

4.

5.f(x)=(x²-1)(x³+1)

=x^5+x²-x³-1

f'(x) =5x⁴+2x-3x²

=5x⁴-3x²+2x

6.f(x)=(2x-6)(3x+5)

=6x²+10x-18x-30

=6x²-8x-30

f'(x)=12x-8

f'(6)=12(6)-8

=72-8

=64

maaf jika ada yg slh
