Question

calcule o seguite limite lim(-x⁵+6x⁴+2)
                                         x=-1

Answer 1

$\lim_{x \to -1} -x^5+6x^4+2 \\ \\ \lim_{x \to-1} -(-1)^5+6(-1)^4+2 \\ \\\boxed{ \lim_{x \to -1} -x^5+6x^4+2 =9 }$

Answer 2

( - (-1)^5 + 6*(-1)^4 + 2 )

- (-1) + 6*(+1) + 2 

+1 +6 + 2 = 9

Logo o limite de (-x^5 + 6x^4 + 2 quando tende a -1 é igual a 9
