Evaluate the following function for the input given below:

  1. `f(6)` when `f (x) = (x^2-4+x)/(7x-5)`.

    `f(6)=`   s

  2. `g(-4.3)` when `g (x) = (-3x^2+1.6x-3(9-x))/(8-2x)`.

    `g(-4.3)=`  

  3. `g(m)` when `g (x) = 2/3x-7x^3+x (x+5)`.

    `g(m)=`  

  4. `f(x+2)` when `f (x) = 5x^2+6x-12`.

    `f(x+2)=`
