Evaluate the following function for the input given below:

1. `f(6)` when `f (x) = (x^2-5+x)/(6x-3)`.

   `f(6)=`   s

2. `g(-5.5)` when `g (x) = (-2x^2+2x-3(7-x))/(7-3x)`.

   `g(-5.5)=`  

3. `g(m)` when `g (x) = 2/3x-6x^3+x (x+5)`.

   `g(m)=`  

4. `f(x+3)` when `f (x) = 2x^2+6x-13`.

   `f(x+3)=`
