I can’t see the images you referenced — could you upload or paste the full problem text and the answer choices?

If the function in question is the common linear function f(x) = m x + b, then the condition for an inverse is that m ≠ 0 (so f is one-to-one). b can be any real number (b = 0 is allowed), and the inverse would be f⁻¹(x) = (x − b)/m.

If the function is a different form (for example a fractional linear function (ax + b)/(cx + d)), the invertibility condition is different (for that one the condition is ad − bc ≠ 0). Upload the problem or choices and I’ll pick the correct choice.
