Question 142996
The solutions to this problem set are actually quite simple.
All we need to do is plug in the given values of x into the function where they occur.


1)   f(4)=1.5(4)-0.4
 At x=4, the function is 5.6


 f(0)=1.5(0)-0.4
  At x=0, the function is -0.4
  

 f(3)=1.5(3)-0.4
 At x=3, the function is 4.1



2)   h(4)={{{3/8}}}(4)+{{{2/3}}}
At x=4, the function is {{{13/6}}}
    
    
     h(0)={{{3/8}}}(0)+{{{2/3}}}

At x=0, the function is {{{2/3}}}


     h(3)={{{3/8}}}(3)+{{{2/3}}}

At x=3, the funtion is {{{43/24}}}



3)   g(4)=-14(3)+5

At x=4, the function is -51


     g(0)=-14(0)+5

At x=0, the function is -5


     g(3)=-14(3)+5

At x=3, the function is -37



4)   k(4)=3.2-5(4)

At x=4, the function is -13.6


     k(0)=3.2-5(0)

At x=0, the function is 3.2


     k(3)=3.2-5(3)

At x=3, the function is -8.6
