Ajutor!!! Dau coroana!!​

Answer 1

Răspuns:

f(-2) = -2•(-2)^2 + 3•(-2) - 1

f(-2) = -8-6-1

f(-2)=(-15)

f(-1) = -2•(-1)^2 + 3•(-1) - 1

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

f(-1)=(-6)

f(-2)+f(-1)=(-15-6)=(-21)

f(0) = -2•0^2 + 3•0 - 1

f(0) = (-1)

f(1) = -2•1^2 + 3•1 - 1

f(1) = -2+3-1

f(1)=0

f(0)-f(1)=(-1-0)=(-1)
