Provide an appropriate response.Prove that the function f is one-to-one.f(x) = 3x - 1
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) = 3a - 1 and f(b) = 3b - 1, we have
3a - 1 = 3b - 1
3a = 3b
a = b
Thus if f(a) = f(b) then a = b and f is one-to-one.
