Question

f(x)= -2×X² +5×X o conjunto é A= -3,-2,-1,0, 1,2,3 ​

Answer 1

Resposta:

-33,-18,-7,-3,0,2,3

Explicação passo a passo:

f(x)= -2×X² +5×X                                             A= -3,-2,-1,0, 1,2,3 ​

f(-3)= -2×(-3)² +5×(-3)=-2*9-15 =-18-15 = -33

f(-2)= -2×(-2)² +5×(-2)= -2*4-10= -8-10= -18

f(-1)= -2×(-1)² +5×(-1)= -2*1-5= -7

f(0)= -2×0 +5×0=0

f(1)= -2×1² +5×1=-2+5=3

f(2)= -2×2² +5×2= -2*4+10=-8+10=2

f(3)= -2×3² +5×3= -2*9+15= -18+15= -3        B= -33,-18,-7,-3,0,2,3
