Question

dada a função f(x)= -(x+3)²-1 calcule f(-2) f(2)

Answer 1

f(-2)= -(-2+3)²-1= -(1)²-1=-1-1=-2
f(2)= -(2+3)²-1= -(5)²-1=-25-1=-26

Answer 2

f(x)=-(x+3)²-1 
f(x)=-(x²+6x+9)-1
f(x)=-x²-6x-10
f(-2)=-(-2)²-6(-2)-10
f(-2)=-4+12-10
f(-2)=-2

f(2)=-(2)²-6(2)-10
f(2)=-4-12-10
f(2)=-26

f(2)*(f-2)= (-2)*(-26)= 52
