1.      f(x)  =  2(x - 1)

        

Using the rule   \(\frac{x^a}{x^b}=x^{a-b}\)  , we have
  f(x)  =  \(\frac{2^x}{2^1}\)

 

 

 
  f(x)  =  \(\frac{2^x}{2}\)

 

 
  f(x)  =  \(\frac12\cdot2^x\)

 

 

Here,   a = 1/2   and   b = 2  .
   

 

 

 
2. f(x)  =  2(3x + 4)

 

Using the rule   xa · xb  =  x(a + b)  , we have
  f(x)  =  23x · 24

 

 

 
  f(x)  =  23x · 16

 

Using the rule   (xa)b  =  xab  , we have
  f(x)  =  (23)x · 16

 

 

 
  f(x)  =  16 · 8x   Here,   a = 16   and   b = 8  .
