The required function from the given options will be 1/5(5x-25)+5: Option B is correct.

Given the functions f(x)=5x-25 and g(x)=1/5x+5, in order to find which expression to be used to verify that they are inverse of each other we will find the composite function g(f(x))

Given the functions

[tex]f(x)=5x-25\\g(x)=1/5x+5[/tex]

g(f(x)) = [tex]\frac{1}{5}(5x-25) - 25\\[/tex]

Note that the function f(x) was directly substituted as variable x in g(x)

Hence the required function from the given options will be 1/5(5x-25)+5
