Soal mtk kelas 11, tolong bantu

Answer 1

Itu yaa kedua jawabannyaa

Answer 2

(32) jika f(x) = 2x^2 - x - 3/ 2x-3

maka, f'(x) =.....?

penyelesaian :
u = 2x^2 - x - 3
u' = 4x - 1
v = 2x - 3
v' = 2

f'(x) = u'v - uv'/v^2
= 4x - 1 (2x - 3) - 2x^2 - x - 3 (2) / (2x - 3)^2
=(8x^2 - 12x - 2x + 3)-(4x^2- 2x) / (2x - 3)^2
=8x^2 - 14x + 3 - 4x^2 + 2x / (2x - 3)^2
= 4x^2 - 12x + 3 / (2x - 3)^2
