Question

Ada yg bisa jawab?makasihh banyakk pakai cara yaa

Answer 1

10.f(x)=x³+5x²+9x
f'(x)=3x²+10x+9
f'(-3)=9-30+9=-12
11.f(x)=2x³+x^(-2)-3
f'(x)=6x²-2x^(-3)-3
f'(x)=6x²-2/x³-3

Answer 2

Basic way buat nurunin fungsi :
X^n (diturunin) n.x^(n-1)
^ = pangkat

10. f(x) = X^3 + 5x^2 + 9x
f'(x) = 3x^2 + 10x + 9
f(-3) = 3(-3)^2 +10(-3) + 9 = 27-30+9 = 6

11. 2x^3 + 1/x^2 -3 = 2x^3 + x^(-2) - 3
f'(x) = 3.2x^2 - 2x^-3 = 6x^2 - 2/x^3
