Question

2) (Valor 2,5) Dada a função f(x) = -2x²+ 3x + 2 e calcule:
a) f(-2)
b) f(-1)
c) f(0)
d) f(1)
e) f(2)​

Answer 1

Resposta:

Explicação passo a passo:

f(-2)=-2.(-2)²+3.(-2)+2=-2.4-6+2=8-6+2=2+2=4

f(-1)=2.(-1)²+3.(-1)+2=2-3+2=-1+2=1

f(0)=2.0²+3.0+2=0+0+2=2

f(1)=2.1²+3.1+2=2+3+2=7

f(2)=2.2²+3.2+2=2.4+6+2=8+6+2=16
