Question

Dada a função f(x) = 2x 4 + 5x 3 + 10x 2 - 12x – 14. A derivada desta função é: A) f’(x) = 8x 3 + 15x 2 + 20x - 12.
B) f’(x) = 2x 4 + 5x 3 + 10x 2 - 12x.
C) f’(x) = 2x 3 + 5x 2 + 10x - 12.
D) f’(x) = 8x 3 + 15x 2 + 20x - 26.
E) f’(x) = 8x 4 + 15x 3 + 20x 2 - 12x - 14.

Answer 1

f(x) = 2x 4 + 5x 3 + 10x 2 - 12x – 14. 

f(x) = 8x 3 + 15x 2 + 20x - 12
