Explications étape par étape

1) g'(x)=9x²-2x

2) g'(x)=15x²+8x-5

3) g'(x)=-12x²-14x+12

4) g'(x)=-3x²+10x-2

INEQUATION

Bonsoir,

Dériver les expressions:

1. g(x)= 3x³-x²+3

g'(x)= 3*3x²-2x= 9x²-2x

2. g(x)= 5x³+4x²-5x+1

g'(x)= 3*5x²+2*4x-5= 15x²+8x-5

3. g(t)= -4t³-7t²+12t-2

g'(t)= -4(3)t²-7(2)t+12= -12t²-14t+12

4. g(q)= -q³+5q²-2q+7

g'(q)= -3 q²+5(2)q-2= -3q²+10q-2
