Evaluate the following function for the input given below:

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

    `f(6)=`   s

  2. `g(-4)` when `g (x) = (-2x^2+1.3x-2(7-x))/(7.1-3x)`.

    `g(-4)=`  

  3. `g(m)` when `g (x) = 2/3x-5x^3+x (x+4)`.

    `g(m)=`  

  4. `f(x+3)` when `f (x) = 2x^2+6x-11`.

    `f(x+3)=`
