Question

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

Answer 1

Resposta:

a)f(0)=

f(0)= x² + 2x + 1

f(0)= 0² + 2.0 + 1

f(0)= 0 + 0 + 1

f(0)= 1

b)f(1)=

f(1)= x² + 2x + 1

f(1)= 1² + 2.1 + 1

f(1)= 1 + 2 + 1

f(1)= 4

c)f(2)=

f(2)= x² + 2x + 1

f(2)= 2² + 2.2 + 1

f(2)= 4 + 4 + 1

f(2)= 9

d)f(-1)=

f(-1)= x² + 2x + 1

f(-1)= -1² + 2.-1 + 1

f(-1)= 1 - 2 + 1

f(-1)= 2

e)f(-2)=

f(-2)= x² + 2x + 1

f(-2)= -2² + 2.-2 + 1

f(-2)= 4 - 4 + 1

f(-2)= 1
