Need as soon as possible! what is the range of f(x)? { f(x)| –∞ < f(x) < ∞} { f(x)| –∞ < f(x) ≤ 4} { f(x)| 4 < f(x) < ∞} { f(x)| 0 ≤ f(x) < ∞}

Choice B) { f(x)| –∞ < f(x) ≤ 4}

Note that { f(x)| –∞ < f(x) ≤ 4} is the same as { f(x)|  f(x) ≤ 4} and that's saying "the output y is at most 4". So the largest y can get is 4. This is the upper limit or ceiling so to speak. The value of y can be any number less than 4.

The range is basically the set of all possible y outputs of a function. It is the set of all y coordinates of the points on the function curve. The highest we can go is y = 4. There is no limit on how low the points can go, so it goes off to negative infinity.
