Question

Sendo f(x)= -x^(2)-3x+1 com x= (-2,-1,0,1,2)​

Answer 1

Explicação passo-a-passo:

f(x) = x^(2) - 3x + 1

f(-2) = -2^(2) - 3(-2) + 1

f(-2) = 4 + 6 + 1

f(-2) = 11

f(-1) = -1^(2) - 3(-1) + 1

f(-1) = 1 + 3 + 1

f(-1) = 5

f(0) = 0^(2) - 3(0) + 1

f(0) = 0 - 0 + 1

f(0) = 1

f(1) = 1^(2) - 3(1) + 1

f(1) = 1 - 3 + 1

f(1) = -1

f(2) = 2^(2) -3(2) + 1

f(2) = 4 - 6 + 1

f(2) = -1
