Resposta:

C. -4

Explicação passo-a-passo:

f(x) = -x² + x - 2

------

f(1) + f(0)

= (-1² + 1 - 2) + (-0² + 0 - 2)

= (-1 + 1 - 2) + (-0 + 0 - 2)

= -2 + (-2)

= -4

paulaana25338: nenhuma probabilidade da conta ser assim: (-1)²+1-2+(-0)²+0-2??? ERREI UMA QUESTÃO NA PROVA
ImFromBrainlyId: can you speak english plss
paulaana25338: No probability of the account being : (-1)²+1-2+(-0)²+0-2??I MISSED A QUESTION ON THE TEST :(
ImFromBrainlyId: From f(x) = -x², it doesn't have brackets, so it means you don't need to put brackets. Give parentheses if the problem already exists, for example: (-x)². And if it is bracketed while in the question it is not, the result will be different.
ImFromBrainlyId: I have a brainly account in Indonesia, I already have more than 100 thousand points and my math answer is 2.5 thousand. So, this is the answer..
paulaana25338: Thanks, next time I'll pay more attention.
ImFromBrainlyId: you're welcome :D
