Question

F(×)-× ao quadrado +x+1

Answer 1

Resposta:

a)

f(x) = x² - x

f(1) = 1² - 1 = 1 - 1 = 0

¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨

Resp.:

f (1) + 3 = 0 + 3 = 3

¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨

b)

R.:

f(-1) - 5 = 0 - 5 = - 5

¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨

f(x) = x² - x

f(-1) = (-1)² - 1 = 1 - 1 = 0

¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨

c)

R.:

f(3) + f(0) = 6 + 0 = 6

****************************

f(x) = x² - x

f(3) = 3² - 3

f(3) = 9 - 3

f(3) = 6

f(x) = x² - x

f(0) = 0² - 0

f(0) = 0
