Question

Dada a função f(x) = 12x – 5, obtenha 

.a) f(–2) =

 b) f(+2) = 

c) f(0) =

 d) f(–1) =

Answer 1

5 ==> - 29


 f(x) = 12x – 5, obtenha 

.a) f(–2) = 12(-2) – 5 ==> - 24 - 5 ==> - 29

 b) f(+2) =  12(2) – 5 ==>  24 - 5 ==> 19

c) f(0) =   12(0) – 5 ==> 0 - 5 ==> - 5

 d) f(–1) =  12(-1) – 5 ==> - 12 - 5 ==> - 17
