Question

Dada a função f(x) = 3x/2 + 1, responda as questões:

a) f(-1) = 3/2 + 1
b) f(0) = 3/2 +1
c) f(1) = 3/2 + 1
d) f(2) = 3/2 + 1

Answer 1

Dada a função f(x) = 3x/2 + 1, responda as questões:

********************************
a) f(-1) = 3.(-1)  + 1  
               --------
                   2

f(-1) = - 3    +  1
          ------
              2

              - 3 + 2
f(-1) =  ----------------
                     2

f(-1) = - 1/2

***************************************
b) f(x) = 3x/2 + 1

f(0) = 3.0  + 1
         ------
            2

f(0) = 0/2 + 1
f(0) = 1

*************************************
c) f(x) = 3x/2 + 1

f(1) =  3.1   + 1
         -------
            2

f(1) =    3  + 1
          -----
             2

           3 + 2
f(1) = -----------
               2

f(1) =   5
          -----
            2

******************************
d) f(x) = 3x/2 + 1

f(2) = 3.2  + 1
         ----- 
            2

f(2) = 6/2 + 1
f(2) = 3 + 1
f(2) = 4
