Answer:
Please check the explanation.
Step-by-step explanation:
Given
a) 
f(x) + g(x) = (2x - 1) + (2 - x)
                 = 2x -1 + 2 - x
                 = x + 1
b)
f(x) - g(x) = (2x - 1) - (2 - x)
               = 2x - 1 - 2 + x
                = 3x - 3
c)
g(-5) - f(-5)
Putting x = -5 in g(x) = 2 - x
g(x) = 2 - x
g(-5) = 2 - (-5) = 2+5 = 7
Putting x = -5 in f(x) = 2x - 1 
f(x) = 2x - 1 
f(-5) = 2(-5) - 1
        = -10 - 1
         = -11
Thus,
g(-5) - f(-5) = 7 - (-11) = 7+11 = 18
d)
f(x).g(x) = (2x - 1) (2 - x) = -2x² + 5x - 2
e)
f(g(x)) = f(2-x)
           = 2(2-x)-1
           = 4-2x-1
           = 3-2x
