a) f(-1)

b) f(0)

c) f(2)​

Answer 2

Explicação passo-a-passo:

Temos a seguinte função $f(x)=-2x^{2} -2$.

a)

$f(-1)=-2.(-1 )^{2} -2\\\\f(-1)=-2.1 -2\\\\f(-1)=-2-2\\\\\boxed{\boxed{f(-1)=-4}}$

b)

$f(0)=-2.(0 )^{2} -2\\\\f(0)=-2.0-2\\\\f(0)=0-2\\\\\boxed{\boxed{f(0)=-2}}$

c)

$f(2)=-2.(2 )^{2} -2\\\\f(2)=-2.4 -2\\\\f(2)=-8-2\\\\\boxed{\boxed{f(2)=-10}}$
