Provide an appropriate response.Prove that the function f is one-to-one.f(x) = 6 - 
x
What will be an ideal response?
Assume that f(a) = f(b) for any numbers a and b in the domain of f.
Since f(a) = 6 - 
a and f(b) = 6 - 
b, we have
6 - 
a = 6 - 
b
- 
a = - 
b
a = b
Thus if f(a) = f(b) then a = b and f is one-to-one.
