No 1 a, b, c pake Cara ya kak please​

Answer 1

Jawaban:

1) a)f(x)=2x^3-3x^2+12x-1

f'(x)=6x^2-6x+12

b)g(x)=(2x^2-x+1)^4

g'(x)= n.U^(n-1).U'

= 4.(2x^2-x+1)^3.(4x-1)

=(16x-4).(2x^2-x+1)^3

c)h(x)=2x+5/x-3

u=2x+5 v=x-3

u'=2 v'=1

h'(x)=u'.v-u.v'/v²

=2(x-3)-(2x+5)1/(x-3)²

=(2x-6)-(2x+5)/(x²-6x+9)

=-11/(x²-6x+9) atau -11/(x-3)²
