Evaluate the following function for the input given below:

1. `f(6)` when `f(x) = (x^2-4+x)/(5x-6)`.

   `f(6)=`   s

2. `g(-5.6)` when `g(x) = (-2x^2+1.7x-3(8-x))/(9-3x)`.

   `g(-5.6)=`  

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

   `g(m)=`  

4. `f(x+3)` when `f(x) = 5x^2+6x-10`.

   `f(x+3)=`
