Evaluate the following function for the input given below:

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

   `f(5)=`   s

2. `g(-5.6)` when `g (x) = (-3x^2+2x-4(8-x))/(7-2x)`.

   `g(-5.6)=`  

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

   `g(m)=`  

4. `f(x+1)` when `f (x) = 5x^2+5x-12`.

   `f(x+1)=`
