Final answer:
The range of the function f(x) = -3x - 1 is (-∞, +∞), meaning that f(x) can take on any real value.
Step-by-step explanation:
The range of a function is the set of all possible values that the function can output. In the given function f(x) = -3x - 1, the range refers to the possible outputs or y-values.
We can find the range by considering the behavior of the function. Since the coefficient of x is -3, we know that as x increases, the value of f(x) will decrease. Similarly, as x decreases, the value of f(x) will increase.
Therefore, the range of f(x) = -3x - 1 is (-∞, +∞), meaning that f(x) can take on any real value.
