functions f and g are defined with their respective domains by

g(x) = 10/x     for real values of x, x is not equal to 0                                                                                      

f(x) =  for x greater or equal to 2.5

a) state the range of f 

b)i) find fg(x)

b)ii) solve the equation fg(x) = 5

c) i) find f^-1(x)

ii) solve the equation f^-1(x) =7
