Question

a derivada da função f(x)= 4 x ^3-7 x ^2+3 x-2 é:
a)2x^2-14x+5
B)x^2-1x+3
c)12x^2-14x+3
D)x^2-14x+11

Answer 1

$f(x)=4x^{3}- 7x^{2}+ 3x-2 \\ \\ f'(x)= 12x^{2}-14 x+3 \\ \\ Letra=\ \textgreater \ C$

Answer 2

a)2x^2-14x+5
f' = 4x - 14

B)x^2-1x+3
f' = 2x - 1

c)12x^2-14x+3
f' = 24x - 14

D)x^2-14x+11
f' = 2x - 14
