Evaluate the following function for the input given below:

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

   `f(6)=`   s

2. `g(-5.8)` when `g(x) = (-4x^2+1.7x-2(9-x))/(8.9-3x)`.

   `g(-5.8)=`  

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

   `g(m)=`  

4. `f(x+4)` when `f(x) = 5x^2+6x-13`.

   `f(x+4)=`
