Question

8) Dada a função f(x)=5-I-2x+1I, calcule: a) f(-2) b) f(0) c) f(6)

Answer 1

Explicação passo-a-passo:

a)

f(-2) = 5 - |-2.(-2) + 1|

f(-2) = 5 - |4 + 1|

f(-2) = 5 - |5|

f(-2) = 5 - 5

f(-2) = 0

b)

f(0) = 5 - |-2.0 + 1|

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

f(0) = 5 - |1|

f(0) = 5 - 1

f(0) = 4

c)

f(6) = 5 - |-2.6 + 1|

f(6) = 5 - |-12 + 1|

f(6) = 5 - |-11|

f(6) = 5 - 11

f(6) = -6
