I don’t have the list of functions you’re choosing from — can you paste the options?
In general, any function of the form y = 3 − g(x) where g(x) > 0 for every x will have range y < 3. Example functions whose range is strictly less than 3:
- y = 3 − e^x. (e^x > 0 for all x, so y < 3; as x → −∞, y → 3 from below.)
- y = 3 − e^{x^2}. (e^{x^2} ≥ 1, so y ≤ 2; in particular y < 3.)
- y = 3 − 1/(x^2 + 1). (1/(x^2 + 1) ∈ (0,1], so y ∈ [2,3), hence y < 3.)
- y = 3 − (x^2 + 1). (x^2 + 1 ≥ 1 so y ≤ 2, thus y < 3.)
If you supply the specific answer choices, I’ll pick which one has range y < 3 and show the reasoning.
